It's good enough that I wouldn't really call it a code generator, and I wouldn't put it in a category with other tools due to the performance different from anything else like it.

Often, it creates code that follows the style of the surrounding environment.

Honestly at this point, the copyright concern seems either ignorant or paranoid to me. The program is interactive and generally only creates small chunks of code at a time. You can read and modify the code it generates (I always do). I only operate on it in digestible chunks, none of which are "original" enough to be considered copyright. Surely, you as a developer can easily say whether the code generated is just some non-copyrightable snippet (some simple BFS code) vs stolen code lifted off a codebase (weirdly specific implementations, fast invsqrt, comments that look like they were written for a different context, magic numbers, undiscovered algorithms).

I would argue that if you can't differentiate between meaningful IP and boilerplate algorithm implementations (with variable names conveniently matching the surrounding context), then you have a different problem.

Yesterday I implemented a BFS in about 30 seconds because copilot recognized the pattern and auto-completed. It took 5 seconds to autocomplete, and 25 seconds to read and fix one line that was wrong. That normally would have taken me 5-10 minutes to code + debug (the copilot code didn't have any errors, minus the 1 I easily found). The productivity gains are too good.
