Absolutely. The problem is that I think 95% of users will not do that unfortunately. I've helped many a dev with some code that was just complete nonsense that was seemingly written in confidence. Turns out it was a blind LLM copy-paste. Just as empty as the old Stack Overflow version. At least LLM code has gotten higher quality. We will absolutely end up with tons of "seems okay" copy-pasted code from LLMs and I'm not sure how well that turns out long term. Maybe fine (especially if LLMs can edit later).

The AIs at the forefront of the current AI boom work by expressing the patterns that exist in their training data.

Just avoid trying to do anything novel and they'll do just fine for you.
