This is a whole different discussion, but I just see it as part of the job that I'm getting paid for, I don't need to enjoy it to do it.

Functional testing is a must now that writing tests is also automated away by LLMs as you can get a better understanding if it does what it says on the box, but there will still be a lot of hidden gotchas if you're not even looking at the code.

Plenty of LLM-written code runs excellent until it doesn't, though we see this with human written code too, so it's more about investing more time in the hopes of spotting problems before they become problems.
