It's in the name "Hacker News". Hackers are people who enjoy doing the programming themselves, because they get satisfaction from it. Often they program in their spare time, and sometimes what they develop has little to no practical value, and is done as a learning exercise. Using AI would defeat the purpose for them. If they're forced to use AI in their job, it decreases their job satisfaction.

There are others who just want a problem solved, and it doesn't matter to them how the program which solves it gets written, as long as the program (appears to) work and it's done as quickly as possible, so they outsource the development to AI. That is not hacking.
