It really depends on what you're doing. AI is great for generating a ton of text at once but only a small subset of programming tasks clearly benefit from this.

Outside of this it's an autocomplete that's generally 2/3rds incorrect. If you keep coding as you normally do and accept correct solutions as they appear you'll see a few percentage productivity increase.

For highly regular patterns you'll see a drastically improved productivity increase. Sadly this is also a small subset of the programming space.

One exception might be translating user stories into unit tests, but I'm waiting for positive feedback to declare this.
