Quick thoughts about never reading the code

Oct 31, 2026

I’ve been thinking about the turning point it seems we’re at with regard to AI code generation and human review - that is, will humans ever read the code moving forward? It sure feels like those days of writing good-looking Ruby are GONE gone. I liked those.

I think all these (contradictory?) things today:

  1. Current LLMs can absolutely do things humans cannot
  2. There is intrinsic value to the code being “good” (in the spirit of the Jobs ‘back of the chest of drawers’ quote)
  3. I’m really uncomfortable using an application where no experienced human ever read the User class. Or the authorization system.
  4. Every great programmer I look up to is fully embracing not needing to read the code
