Dev calls out Anthropic for not shipping built-in memory wiki — because it sells tokens

arieljalali · x · 2026-10-31

Quoting a viral post: devs waste 20 minutes every morning re-explaining their project to Claude Code, even though Karpathy showed the fix a year ago — use AI to build a "second brain" instead of just writing code. Point Claude Code at an Obsidian vault, drop in articles, transcripts, PDFs, and it builds a living wiki that compounds as you feed it more.

The author's take: Anthropic could easily build this wiki/memory into Claude, but doesn't — "because they sell tokens." Re-prompting context is itself a revenue source.
