I have two that flip for my favorite depending on my mood at any given time: “There Will Be Blood” and “Blade Runner 2049”. They are both kinda slow and require attention to really appreciate, so probably my favorite movie to turn my brain off and have fun is “Mad Max: Fury Road”.
I haven’t used it often, but the few times I have asked it very specific programming questions, it has usually been pretty good. For example, I am not very good with regex, but I can usually ask Copilot to create regex that does something like verifying a string matches a certain pattern, and it performs pretty well. I don’t use regex enough to spend a lot of time learning it, and I could easily find a few examples online that can be combined to make my answer, but Copilot is much quicker and easier for me. That said, I don’t think I would trust it past answering questions about how to implement a small code snippet.
