AI can only really complete tasks that are both simple and routine. I’d compare the output skill to that of a late-first-year University student, but with the added risk of halucination. Anything too unique or too compex tends to result in significant mistakes.

In terms of replacing programmers, I’d put it more in the ballpark of predictive text and/or autocorrect for a writer. It can help speed up the process a little bit, and point out simple mistakes but if you want to make a career out of it, you’ll need to actually learn the skill.
