It's not really any different in programming. Like if you have a well structured code and want to do a clear refactoring across it and you know what to expect, it can speed things up. But if it's generating any significant (and relatively complex) new code, you have to go through the whole thing manually again and then you find out you have to fix way to many things and get bogged down in different paths the AI didn't do correctly.

Of course, it's pretty much impossible to hear a dissenting point of view today and everyone is going crazy on these drugs. I might be hilariously wrong but I think this is the best time to start a software company.
