Faster, Please! • 274 implied HN points • 06 Dec 25
🚌 Education Technology

💼 Business Technology
  1. The idea that AI-driven productivity will cause a 2028 market crash is implausible because it doesn't show how rising productivity would suddenly collapse demand.
  2. Large productivity gains that raise most people's real incomes are more likely to boost consumption than push the economy into a liquidity trap.
  3. It's reasonable to worry about real risks from AI, but 'too much productivity growth' isn't one of them — turning good news into a macroeconomic disaster is a rhetorical trick.

Working Hard or Hardly Working

Some Unpleasant Arithmetic • 24 implied HN points • 12 Feb 26
🎭️ Culture Technology
  1. Market-driven economic change uproots communities and erodes social bonds, which lowers trust and can produce crime, political backlash, and long-term despair.
  2. Work has become a central source of identity, driving grind culture and extreme hours that cause burnout and are often counterproductive, while also deepening inequality and gender gaps.

Be Present

The Analog Family • 559 implied HN points • 25 Apr 24

Why Sharding?

Dan Hughes • 239 implied HN points • 24 Jun 24
🔮 Crypto Technology
  1. Sharding is a great solution for scaling blockchain networks. It allows the system to handle more transactions by dividing tasks into smaller pieces, making processing faster and more efficient.
  2. Relying solely on improving hardware to scale blockchain systems is not enough. It can lead to problems with latency and conflicts that slow down the network as demand increases.
  3. Atomic commitment in sharding ensures that transactions across different parts of the network can be completed all at once or not at all. This helps keep the system clean and prevents messy issues when something goes wrong.

Faster, Please! • 1005 implied HN points • 23 Jul 25
🇺🇸 U.S. Politics Technology

2025 Is Finally Over—But Not Soon Enough

Slack Tide by Matt Labash • 154 implied HN points • 30 Dec 25
🎭️ Culture Technology

  3. Keep writing and creating even when you feel malaise, because it helps clarify thought and can be its own reward; small humane acts and humor in hard times also give real inspiration and steadiness.
