We can significantly reduce the impact of the next pandemic by upgrading building ventilation standards

Steve Kirsch's newsletter • 4 implied HN points • 22 Jan 26
🏥 Health Politics Infrastructure
  1. Upgrading building ventilation to modern standards—combining rapid air mixing with dilution from fresh air, high-efficiency filtration, or UV—makes indoor aerosol transmission of respiratory viruses highly unlikely.
  2. These upgrades are very cost-effective and practical: one-time or incentivized investments (retrofitting HVAC, portable purifiers, etc.) cost far less than pandemic losses and provide lasting protection against future outbreaks.
  3. Public health responses focused on closures and behavior instead of air quality; simple, low-cost steps like smoke tests, opening windows, improved filtration, and tax/loan incentives would keep schools and businesses safer without disruptive lockdowns.

Grid Upgrade - Part 1: the reasons

GEM Energy Analytics • 139 implied HN points • 07 Sep 23
🌞 Climate & Environment Infrastructure
  1. We need to upgrade our electricity grid because electricity use is rising with new technology and applications. This includes electric cars and heating, which all require more power.
  2. The grid must handle a lot more energy generation from renewable sources like wind and solar. This means we need to build more infrastructure to support the increased output.
  3. Many new energy projects are located far from where the electricity is needed. To solve this, we must improve connections and cooperation between regions to reliably deliver energy where it’s required.

Grid Upgrade - Part 2: what lies ahead

GEM Energy Analytics • 139 implied HN points • 19 Sep 23
🌞 Climate & Environment Infrastructure
  1. The electricity grid is growing slowly and facing congestion. This means it may get overcrowded and not work as well as it should.
  2. Local opposition can delay grid projects, making them take longer and cost more. People sometimes do not want new lines near their homes, which leads to complications.
  3. Grid fees are likely to increase as upgrades are needed. As more money is spent on improving the grid, utility bills may go up for everyone.

Recursive Language Models ("RLMs")

Why Now • 7 implied HN points • 09 Jan 26
🕹 Technology Infrastructure
  1. Models suffer from "context rot" on very long inputs: attention gets diluted, positional signals degrade, and small mistakes compound over long sequences.
  2. Recursive Language Models (RLMs) handle long context by having a root model peek, create targeted context slices, spawn sub-models to summarize or process each chunk, and then combine results, so each model sees much less context.
  3. RLMs have shown strong empirical gains and cost savings on long-context benchmarks, and they could enable scalable codebase reasoning, long-running assistants, and other tasks that need effectively unlimited context.
