The Shape of AI: Jaggedness, Bottlenecks and Salients

One Useful Thing • 1423 implied HN points • 20 Dec 25
🕹 Technology Innovation
  1. AI ability is jagged: it can be superhuman at some tasks (like reasoning or math) and weak at others (like memory or simple real-world interactions), so humans and AI will often end up complementing each other.
  2. A single weak link can bottleneck an entire process, and those bottlenecks can be technical or institutional; when a lab fixes a key bottleneck (a "reverse salient") the whole system can leap forward.
  3. Fixing bottlenecks can cause sudden lurches—better image generation already unlocked automated slide creation—yet humans will still be needed for edge cases, social coordination, and tasks requiring memory or physical action, so changes will be uneven and create new opportunities.
