2025: The Year in Review

Gonzo ML • 252 implied HN points • 06 Jan 26
🕹 Technology Infrastructure
  1. 2025 was the year of agents — they’re being built into every product and API, but many still fail often and lag traditional reliability standards, so expect more focus on making them robust.
  2. Code agents and agentic tools for science made big practical gains, with autonomous multi-step work across repositories and early successes in automated research and math.
  3. The hardware and model landscape shifted: TPUs and strong Chinese open models reduced dependence on a single vendor, AGI hype cooled with timelines pushed out, and world-model research kept advancing.

Google could become a major security player in the next few years

Frankly Speaking • 50 implied HN points • 12 Feb 26
🕹 Technology Infrastructure
  1. Google could become a major security player by consolidating essential "plumbing" tools like SSO, EDR, and email into a neutral infrastructure layer, with Wiz providing visibility and Gemini automating workflows. This would let builders customize and remediate problems instead of battling closed, admin-focused tools.
  2. AI is collapsing the per-seat SaaS and point-product model; security must scale with code, agents, and automation rather than more headcount. Organizations that automate extensively shorten breach lifecycles and lower costs.
  3. Google’s vertical integration—cloud, Workspace, and a powerful AI model—plus usage-based pricing and targeted acquisitions could make it a builder-friendly alternative to legacy security vendors. That positioning plays to engineers who want API-first, customizable infrastructure rather than proprietary, admin-heavy systems.

The Venezuela Opportunity

Not Boring by Packy McCormick • 119 implied HN points • 22 Jan 26
🌍 World Politics Infrastructure
  1. Venezuela is a massively underpriced opportunity beyond oil — if rebuilt and democratized it could join Colombia, Panama, and Ecuador as a powerful nearshoring bloc and a strategic partner to the U.S., unlocking big trade and job gains.
  2. Modern infrastructure, reliable dispatchable power (notably hydropower), and U.S.-backed financing and institutional reform are the keys to attracting hyperscale data centers, manufacturing, and long-term investment.
  3. Venezuelan entrepreneurs and an 8M-strong diaspora have already shown leapfrog innovation (e.g., Cashea), but private firms will scale up only once political and legal risks meaningfully decline.

If apps are dead, is context the new moat?

Kathy PM • 13 implied HN points • 09 Mar 26
🕹 Technology Infrastructure
  1. Building standalone apps as destinations is becoming obsolete because people don't want to leave their existing workflows. Software now needs to show up where users already are.
  2. Low-cost, fast-built "vibe" apps will flood the web but most won't earn long-term value because they don't accumulate context. The real advantage is owning continuous context — memory over time, visibility across tools, governed actions, and trust.
  3. The future is continuous systems that observe work, accumulate context, and proactively help inside your existing tools. These always-on, mostly invisible layers prioritize continuity and background improvements over flashy interfaces.

The API Changelog • 1 implied HN point • 17 Mar 26
🕹 Technology Infrastructure
  1. AI agents are becoming first-class users of APIs, with programmable banking and agent-native email that let agents act autonomously.
  2. New infrastructure is emerging to discover, control, and secure agent traffic — think unified control planes, MCP registries, network-level authentication, and API-based threat detection.
  3. Companies need to treat APIs as programmable products and invest in AI-readiness, standard identifiers, and one-click integrations so agents can reliably and safely consume services.

Cloud War: the National Security Strategy Edition

Interconnected • 339 implied HN points • 07 Dec 25
🌍 World Politics Infrastructure
  1. U.S. embassies are now being tasked to promote American companies and steer government contracts to them, even working to push foreign firms out of infrastructure deals in places like Latin America.
  2. Cloud data centers are being treated as critical infrastructure and a major front in U.S.–China competition, with Chinese cloud providers expanding fast across the Western Hemisphere.
  3. U.S. foreign policy has shifted from pushing democracy to prioritizing pragmatic commercial and strategic goals, so diplomats will focus more on making deals and selling American tech than on regime type or election promotion.

Africa in 2024

An Africanist Perspective • 2117 implied HN points • 01 Jan 24
🌍 World Politics Infrastructure
  1. Africa in 2024 will see tough economic times, with debt distress, moderate growth, and challenges in inflation and household purchasing power.
  2. Several African countries will hold pivotal elections in 2024, with notable contests in Botswana, Ghana, Mozambique, Namibia, Senegal, and South Africa.

  3. Investing in HS2 will help relieve pressure on existing train lines, allowing for more local services and better freight transport, which is crucial for overall infrastructure.

Nuclear Power Needs Realism And Freedom

QTR’s Fringe Finance • 23 implied HN points • 01 Mar 26
🇺🇸 U.S. Politics Infrastructure
  1. Nuclear power in the U.S. has relied on heavy federal support and strict regulation, which helped cause uncompleted projects, big cost overruns, and made it an expensive way to produce electricity without subsidies.
  2. New reactor promises, including Small Modular Reactors, are getting a lot of hype but carry unclear risks and contractual fine print, so their timeliness and cost performance should be questioned.
  3. The proposed policy approach is to end federal subsidies and insurance, shift to private insurance and industry best practices, and make plant owners responsible for waste and decommissioning so the market can decide competitiveness.

The Birth of the Grid

Construction Physics • 19834 implied HN points • 25 May 23
🕹 Technology Infrastructure

AI is just the latest Monoculture

Deus In Machina • 72 implied HN points • 05 Feb 26
🕹 Technology Infrastructure
  1. Technological lock-in has been the default for decades, so AI tools are more inheriting existing monocultures than creating them. They might speed up adoption of dominant tools, but the fundamental switching costs already existed.
  2. Products and tools tend to win by being familiar, not necessarily by being better, because people avoid relearning interfaces. That’s why many improvements preserve old APIs and conventions instead of introducing new paradigms.
  3. Concrete chokepoints — like the C ABI, curly-brace syntax, dominant CPU/GPU ecosystems, and the browser stack — show how early choices constrain future innovation. Those entrenched standards make it hard for new languages, hardware, or platforms to gain traction even before factoring in AI.

Layer 3 Deep Dive

DeFi Education • 399 implied HN points • 12 Jun 24
🔮 Crypto Infrastructure
  1. Layer 3 is the application layer that helps make blockchain technology user-friendly. It aims to simplify how people interact with decentralized finance (DeFi) and other crypto apps.
  2. Layers 1 and 2 are the foundational blockchains, but most users won't need to understand them. The goal is to focus on user experience rather than the underlying complexity.
  3. To bring crypto applications to a wider audience, it’s important to extend and enhance existing technologies, making them more accessible to everyone.

The Sequence Radar #795: The New Inference Kids

TheSequence • 112 implied HN points • 25 Jan 26
🕹 Technology Infrastructure
  1. Serving models (inference) is now the main battleground, drawing huge funding as startups race to make model serving boring, reliable, and infinitely scalable.
  2. New kernel-level tricks are cutting recomputation and memory waste: RadixAttention reuses KV cache blocks like an LRU to avoid recomputing prefixes, and PagedAttention pages KV memory so GPUs can pack many more requests without VRAM fragmentation.
  3. Latency and per-turn cost now define product quality, causing a split in the stack between orchestration/hardware layers that manage scale and kernel teams that squeeze every FLOP to make models fast and cheap.

For 14 years, a crazy eco-terrorist group has attacked Berlin's energy infrastructure with impunity. Authorities have done nothing despite enormous damages and wide-scale disruption. What is going on?

eugyppius: a plague chronicle • 171 implied HN points • 06 Jan 26
🌍 World Politics Infrastructure
  1. An eco-terrorist group called the Volcano Group has been attacking Berlin's power network for about 14 years, and their latest strike triggered one of the largest sustained blackouts in the country's history.
  2. The outage hit tens of thousands during an arctic cold snap, causing loss of heating, burst pipes, health risks for vulnerable people, and empty, unlit neighborhoods that invite looting.
  3. Authorities and security services have responded slowly and weakly — repairs took days, media attention was muted, and past suspects were quickly released, which has allowed the saboteurs to operate with apparent impunity.

Ronin’s Saigon Testnet is migrating to Ethereum!

Ronin’s Newsletter • 61 implied HN points • 03 Feb 26
🔮 Crypto Infrastructure
  1. Saigon Testnet will hardfork and migrate onto Ethereum via Optimism at block #45528550 on Feb 5, 2026, and the testnet Chain ID will update to 202601.
  2. Users don’t need to do anything — games, apps, and the Ronin Wallet will keep working, and bridging and in‑app swaps will remain available.
  3. Builders must upgrade RPC nodes before the hardfork and expect about eight hours of downtime. Running Saigon as an L2 after migration requires reth and op-node and launching from the provided state snapshot.

Clouded Judgement 3.6.26 - Get in the Token Path

Clouded Judgement • 16 implied HN points • 06 Mar 26
💼 Business Infrastructure
  1. The biggest cloud-era infrastructure winners aligned their revenue with the platform's core consumption unit — they "owned the meter" so more usage automatically meant more revenue.
  2. In AI, tokens are becoming that core unit, so companies directly in the token path (models, inference platforms, and coding agents) can structurally scale as token consumption rises.
  3. Being in the token path is necessary but not sufficient — companies must build real differentiation and moats (better developer UX, vertical models, security/compliance, or proprietary data) and move quickly before token economics commoditize.

Six Things to Know About Your Electric Utility

The Honest Broker Newsletter • 3179 implied HN points • 30 Jan 25
🌞 Climate & Environment Infrastructure
  1. Utilities have to serve everyone in their area, which limits how much risk they can take on new technologies. They often focus on proven ideas to avoid wasting customer money.
  2. Community opposition can make it really hard for utilities to expand infrastructure. This can slow down projects that are important for energy needs, as people often don’t want facilities near them.
  3. The push for renewable energy is complicated. While renewables can be cheaper, the technology for storing energy isn't perfect yet, leading utilities to still rely on fossil fuels during certain times.

☀️ A California dream that should come true

Faster, Please! • 365 implied HN points • 20 Nov 25
🇺🇸 U.S. Politics Infrastructure
  1. Neom, the ambitious megacity in Saudi Arabia, is facing serious financial and engineering challenges, leading many to doubt its feasibility. What was once a grand vision is now more about managing expectations as costs spiral out of control.
  2. California Forever aims to build a new city for 400,000 people and shift its focus from just housing to creating jobs and workforce opportunities. This approach could make the project more appealing and practical for future residents and investors.
  3. The project must navigate a complicated political and regulatory process to succeed. Delays caused by environmental reviews and local governance could hinder its progress, showing that growth initiatives often struggle in California's bureaucratic landscape.

Nobody is shipping your agent’s code (yet) | Predictions from LinearB’s Ori Keren

Dev Interrupted • 56 implied HN points • 03 Feb 26
🕹 Technology Infrastructure
  1. AI has erased the blank-page problem and speeds up code generation, but those upstream gains are being lost to chaotic code reviews, testing, and integration unless teams build proper infrastructure.
  2. Agentic tools that can control your local machine (like OpenClaw/Moltbot) show huge power but create major security and governance risks, so most organizations won’t give them autonomous control yet.
  3. The economics of software are shifting: survival favors substrate-efficient tools and firms with unique data or "insight compression," and the current "dark flow" of vibe coding can make teams feel faster while actually introducing hidden bugs, so risk-aware pipelines and better testing are essential.

33 predictions for 2026 in AI: consumer, enterprise, AI capex, and more

Engineering Liveness

Breaking Smart • 50 implied HN points • 01 Feb 26
🕹 Technology Infrastructure
  1. A 'useless machine' models a kind of liveness: things that exist to control their own state and resist being captured or made to serve external purposes.
  2. New Nature will look like a technological tangled bank — messy, competitive, and often secretly violent — so rewilding civilization means accepting risk, death, and illegible forms of competitiveness instead of sanitised spectacle.
  3. Liveness means reserving resources for self‑continuation and choosing to exist without proving usefulness; it’s about playing the infinite game and resisting being absorbed into finite goals.

Pushing The Envelope In Crypto

Points And Figures • 239 implied HN points • 12 Dec 25
🔮 Crypto Infrastructure
  1. Bitnomial launched a regulated crypto-margined exchange that lets traders use crypto as margin and settle trades in crypto. That enables deliverable perpetual futures instead of cash-settled contracts.
  2. They built a vertically integrated exchange and clearinghouse from scratch and are fully regulated by the CFTC, so positions are cleared and collateral is segregated like traditional futures. The team running it are industry veterans, not fly-by-night operators.
  3. New CFTC and OCC guidance allows independent and bank-affiliated brokerages to support crypto margin deposits and settlement, which could unlock capital efficiencies and wider access for US traders. This makes leveraged spot, perpetuals, and options with crypto-native margin more accessible without going offshore.

🕹 Technology Infrastructure
  1. PayPal operates a massive Kafka system with over 85 clusters and handles around 1.3 trillion messages daily. They manage data growth by using multiple geographical data centers for efficiency.
  2. To improve user experience and security, PayPal developed tools like the Kafka Config Service for easier broker management and added access control lists to restrict who can connect to their Kafka clusters.
  3. PayPal focuses on automation and monitoring, implementing systems to quickly patch vulnerabilities and manage topics, while also optimizing metrics to quickly identify issues with their Kafka platform.

Britain still isn't moving fast enough

Odds and Ends of History • 1474 implied HN points • 11 Jun 25
🇺🇸 U.S. Politics Infrastructure
  1. Building infrastructure in Britain is taking way too long, with projects like HS2 getting pushed back to 2036 or later. This is frustrating for people who want improvements now.
  2. Despite the government announcing plans to speed things up, the actual timelines for construction are still disheartening. Many projects won't be finished until 2040 or later.
  3. There's a disconnect between politicians making infrastructure decisions and seeing real changes in communities. Voters deserve to see results during their elected leaders' terms.

HS2: The day they cancelled the 21st Century

Striking 13 • 2176 implied HN points • 04 Oct 23
🌍 World Politics Infrastructure
  1. HS2 project cancellation in the UK is criticized for hindering progress and development, especially in terms of infrastructure, economy, and environmental impact
  2. HS2 aimed to address capacity issues in the existing rail system, improve connectivity, and contribute to environmental sustainability by reducing carbon emissions from travel
  3. The decision to cancel HS2 is seen as short-sighted, as it not only fails to save money but also overlooks the long-term benefits and potential financial gains of the project

The National Parking Platform is a big, exciting deal and you should know about it

Odds and Ends of History • 1608 implied HN points • 22 May 25
🇺🇸 U.S. Politics Infrastructure
  1. The National Parking Platform (NPP) is a new data system that makes paying for parking easier by allowing any payment app to work with any car park. This means you won't have to download many apps just to park your car.
  2. This platform collects data from all car parks, which helps local authorities manage parking better and reduce traffic by making sure spaces are used efficiently.
  3. The NPP could lead to new ways of thinking about parking, like offering discounts for electric cars or using real-time data to help drivers find available spots before they arrive.

18 Predictions for 2026

Jakob Nielsen on UX • 116 implied HN points • 13 Jan 26
🕹 Technology Infrastructure
  1. 2026 is the Integration Era: AI stops being a party trick and gets embedded into work and products through autonomous agents, generative UIs, and multimodal/physical capabilities. User experience and agent management, not raw model IQ, become the primary business differentiators.
  2. A compute-driven two-tier world will emerge: persistent shortages and costly inference mean premium subscribers get powerful, multimodal agents while most people use weaker, eco-models. This forces tiered pricing, compute-aware product design, and widens professional and economic divides.
  3. Human roles shift toward judgment, oversight, and trust work: people will focus on setting goals, auditing agent decisions, designing guardrails, and training via apprenticeships. New risks like AI-powered dark patterns will create demand for defensive agents, governance, and stronger UX ethics.

The Unbreakable Message

Who is Robert Malone • 15 implied HN points • 28 Feb 26
🕹 Technology Infrastructure
  1. Quantum communication uses quantum physics to make eavesdropping detectable, so intercepted messages can't be silently copied or later decrypted. This prevents the "harvest now, decrypt later" threat.
  2. Militaries, intelligence agencies, and banks are prioritizing quantum links for the most sensitive communications because the technology can provide a lasting strategic advantage. Whoever builds the networks and standards first could shape the global information architecture and force others to choose sides.
  3. Practical limits remain—photons are lost in fiber, quantum repeaters are needed, and current hardware is expensive and low-bandwidth—so broad consumer use is likely decades away. Once repeaters and miniaturization mature, a quantum internet and distributed quantum computing could reshape security, finance, healthcare, and science.

Many Victorian cities grew by tenfold in a century

The Works in Progress Newsletter • 55 implied HN points • 03 Feb 26
💾 History Infrastructure
  1. Cities in the nineteenth century grew hugely while getting better: wide, connected street networks, modern sewers, running water and mass transit let homes become larger and more affordable relative to incomes.
  2. Governments used regulated monopolies, concessions or municipal companies and charged users enough to pay for big upfront costs. That alignment of private profit and public benefit let operators build coherent, non‑duplicative networks.
  3. Since 1914 many of those arrangements unraveled and were replaced by zoning, price controls and subsidies, which slowed growth and worsened housing affordability. Cities that want faster growth and more housing should consider permissive building rights, coordinated street planning, and financing models that align private incentives with public goods.

America Needs to Go Nuclear. Plus. . .

Common Sense with Bari Weiss • 788 implied HN points • 20 Aug 25
🇺🇸 U.S. Politics Infrastructure
  1. America needs more reliable energy sources like nuclear power. The current energy grid is weak and cannot keep up with demands.
  2. The U.S. relies on Russia for uranium used in nuclear plants, but this will change with upcoming import bans. There are new private efforts to enrich uranium domestically.
  3. Nuclear energy is gaining attention as a clean option and can help alleviate fears of energy shortages, especially among younger generations concerned about climate change.

The Miracle Man of Suez

Kvetch • 43 implied HN points • 07 Feb 26
💾 History Infrastructure
  1. A single leader's stubborn, relentless will can push an audacious engineering project past political and technical barriers.
  2. Monumental success required new machines, massive labor, and clever engineering, but it came at a terrible human cost and nearly bankrupted local authorities.
  3. Selling shares to thousands of small investors can raise huge sums and build public support. But relying on that and on personal confidence while downplaying engineering and financial risks can lead to ruin.

My 5 Favorite Not Boring Essays of 2025

Not Boring by Packy McCormick • 146 implied HN points • 23 Dec 25
🕹 Technology Infrastructure
  1. Electric technology is rapidly getting cheaper and better, so electric products will increasingly outperform combustion and enable new things; where and how components are made will shape who wins.
  2. Technology expands our capacity but doesn’t create meaning for us, so we must choose how to spend our extra hours by paying attention, seeking novel experiences, and building relationships.
  3. There’s huge opportunity in real differentiation and craft amid widespread copycat slop, and as AI commoditizes routine tasks humans win by moving up the stack into creative, relational, and higher‑level work done with joy and purpose.

⚙️ How to Set Up OpenClaw (The Complete Guide — From Free to Paid)

The Product Channel By Sid Saladi • 33 implied HN points • 18 Feb 26
🕹 Technology Infrastructure
  1. You need two things to run OpenClaw: a machine (Mac, Linux, VPS, or even an old laptop) and an LLM API key, and you’ll also need an account on a messaging app (WhatsApp, Telegram, Slack, or Discord) to connect to it.
  2. One-click cloud deploys are the easiest paid route — DigitalOcean is the most polished option for security and convenience, while Contabo offers the best value for low-cost VPS resources.
  3. Oracle Cloud’s Always Free tier is the best free hosting option, giving up to 4 ARM cores, 24 GB RAM, and 200 GB storage so you can run OpenClaw at no monthly cost; setup typically takes about 30–45 minutes.

India’s AI Wedding Buffet: Generous Portions, Political Economy Heartburn

Get Down and Shruti • 20 implied HN points • 16 Feb 26
🕹 Technology Infrastructure
  1. The government favors an innovation-first, light-touch AI governance model that leans on existing laws, sector regulators, and techno-legal standards, and it has already moved to impose binding deepfake rules; but enforcement capacity and institutional scaffolding lag behind the rules, risking overreach or automated over-removal.
  2. Physical and political-economy constraints—notably soft soil at fab sites, slow and complex subsidy disbursements, and an insolvent, politically distorted electricity distribution system—are the real bottlenecks that will decide whether AI chips, data centers, and other infrastructure actually get built.
  3. India has world-class engineering talent and a strong startup ecosystem that can build niche, language- and document-focused models and do the messy systems integration work enterprises need, but unpredictable tax rulings, bureaucratic grant processes, and limited private capital certainty make it hard for companies to scale to global frontier models.

NYC Congestion Pricing: Early Days

Don't Worry About the Vase • 2732 implied HN points • 14 Jan 25
🇺🇸 U.S. Politics Infrastructure
  1. Congestion pricing in NYC means drivers now pay $9 to enter Manhattan below 60th Street. This fee is aimed at reducing traffic and will increase over time.
  2. Traffic in and around Manhattan has improved since congestion pricing started. Travel times through tunnels have dropped significantly, leading to less congestion overall.
  3. While some people support the changes, others feel negatively about them. There are concerns that fewer cars mean fewer people in some areas, impacting local businesses.
