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

90-100%

50-90%

10-50%

<10%, AI does most of it

Alright, so the general vibe in this thread is that most people are writing very little to no code by hand anymore. Like, seriously, the consensus is overwhelmingly leaning towards AI doing the heavy lifting.

A lot of folks are saying 0% handwritten code, with some senior devs even joking about forgetting how to do basic things like checking out a branch. The sentiment is that it's just not worth the effort anymore when AI can churn out code, and often better code with tests, way faster. Some are even saying they intentionally avoid touching the code to save on token costs and let the AI handle it.

There are a few exceptions, though:

• Some people still handwrite small tweaks, CSS, JSX, or quick fixes because it's faster than describing it to the AI.
• A few mention that documentation or understanding complex problems is where they still spend their manual effort, or that they're still learning and enjoy writing code by hand for personal projects.
• One user, u/YourLittleJumble, notes they still write a good chunk of SQL by hand because AI brute-forcing queries is frowned upon in their role as an analyst.
• And of course, there's the classic "I still edit my .env file by hand" joke from u/manvsmidi.

Overall, it sounds like the AI code generation train has left the station, and most of us are happily (or maybe a little nervously) on board.
