My co-workers have tried to convince me, but all I've seen are a handful of funny and weird results. I haven't actually seen a real productivity improvement.
In fact, I recently did an interview and let the candidate use copilot, and they pretty much bombed because they relied way too much on the tools. Copilot made an obvious mistake, I had to point it out, then they repeated that exact same mistake later on without noticing. LLMs like copilot make stuff up and get stuff wrong enough to be a serious issue.
I personally don't see much value in it, and I see a large potential for relying too heavily on it and making obvious mistakes. Then again, I haven't personally used it, so maybe I don't know what I'm missing. There's no harm in trying it out, just be skeptical and don't drink the Kool aid. Then again, I'm a Linux using nutjob that would probably be yelling at clouds if I didn't work indoors.
