Umm. Just no. A lot of what I do at work, AI can help only in minimal ways. I know this because some people insist on using it, and I'm always seeing their trash PRs. Because it's just no good with such specific stuff where it can really only try to find generic solutions.
While I think the visual studio and similar auto completion stuff to be awesome stuff. The internal tooling we have to write code doesn't have this and guess what, we're doing fine.
But then I don't work in a game studio. I cannot say how it is in that industry.
Is it convenient for a lot of things? Sure it is. But, you know I try to avoid it for my own personal stuff, just so I keep the brain cells that are there for software development, active and able to do it unassisted.
