I use AI all the time, but the only gain they have is better spelling and grammar than me. Spelling and grammar has long been my weak point. I can write the same code they write just as fast without - typing has never been the bottleneck in writing code. The bottleneck is thinking and I still need to understand the code AI writes since it is incorrect rather often so it isn't saving any effort, other than the time to look up the middle word of some long variable name.
