I would love to hear from other people here but I tried it for a while and dropped my subscription. For short things it was nice, but the larger the suggestion the worst it got. I found myself constantly mentally debugging the output it suggested, I do not know if it was faster but I was mentally exhausted by it, unable to go for long periods of time. Dumb code completion is predictable, I know I'll need to press dow…
I can understand why you might not like it if you were using it for critical things that needed to be well planned and debugged before running. I don't find it very good at intricate work but that's ok with me since I want to really slow down at those points and think about what I'm doing.
As a side note, using ChatGPT with GPT-4 or even just GPT turbo is an amazing unblocker for projects where you need to use unfamiliar packages, APIs or languages. You can just talk to it about what you're trying to do and it'll provide you with great examples and explanations. It won't be right 100% of the time but it's right enough to get you unstuck and a lot faster than searching through docs or stackoverflow for a good answer. It helps to be very precise with your problem statement as well, like specifying the version of the package you want to use or a time frame. Those little prompt tricks remind me a lot of the Google-fu we had to learn to search effectively. I'm excited that Copilot is going to be moving to GPT-4 with chat built in, it'll unify the whole process.
