Meir's Monthly Learning Article

This month I want to highlight a late-December tweet, by Boris Cherny, the creator of Claude Code. Boris notes that in the past month 100% of his contributions to Claude Code were written by Claude Code.

This accomplishment reminds me of compiler bootstrapping – where new programming languages can eventually create compilers written in their own language to compile themselves. This is a natural progression for serious programming languages, and it is fascinating to see a thematic parallel with Gen AI coding assistants.

I suspect this tweet marks an inflection point in coding assistants, proving their validity and expanding their reach. It also hints at the broader, non-coding LLM self-improvement use cases and increases my curiosity about how much control humanity will retain over AI’s future.

“A year ago, Claude struggled to generate bash commands without escaping issues. It worked for seconds or minutes at a time…Fast forward to today. In the last thirty days, I landed 259 PRs — 497 commits, 40k lines added, 38k lines removed. Every single line was written by Claude Code + Opus 4.5.”
