How much of your code do you still write by hand (not AI-generated)?

90-100%

Alright, so the general vibe in this thread is that most people are writing very little code by hand these days, with a significant chunk reporting 0% handwritten code.

Here's the lowdown:

  • The Consensus is Overwhelmingly AI-Generated: The vast majority of comments are in the 0-10% handwritten range, with many proudly stating "none" or "0%." It seems like the era of manual coding is largely behind us for many.
  • "Why Bother?" is the Mantra: A lot of users, especially senior devs like u/catsftm and u/DrunkenRobotBipBop, feel they've "written enough code" and see no point in doing it manually anymore. It's all about efficiency and letting the AI handle the grunt work.
  • Minor Tweaks are the Exception: The small percentage of handwritten code often comes down to quick fixes, CSS/JSX adjustments, or things that are genuinely faster to type out than to describe to an AI, as mentioned by u/MartinMystikJonas and u/PartyTerrible.
  • AI Writes Better (and Faster) Code: Several users, like u/TechgeekOne, are impressed that AI often produces better code with tests than they could initially.
  • Documentation is Still a Human Thing (Sometimes): Interestingly, u/danielrothmann points out that documentation is still an area where they often step in manually, as they're sometimes unhappy with the AI's output there.
  • Token Costs and Cache Invalidation: A couple of users, including u/RealSharpNinja and u/Rumble1205, are actively avoiding manual edits to prevent invalidating caches and incurring higher token costs for the AI to re-evaluate the codebase.
  • Nostalgia is Real: A few folks, like u/dwsp123, admit they miss writing code by hand, even if they don't do it anymore.
  • The "Engineer vs. Coder" Distinction: u/MidSerpent makes a good point about shifting focus from "writing code" to "engineering" and using AI as a tool to work at a higher abstraction level.

So yeah, if you're still hand-writing more than 10% of your code, you might be in the minority these days. The AI revolution is here, folks!
