It's very good at translating between programming languages, including pseudocode.
It can write a lot more valid code much quicker than any human, and in a whole slew of languages.
I haven't had the urge to use it much after playing around with it constantly for a few days, but it was pretty mind-blowing.
When I was playing around a couple years ago with the Fastai courses in language modeling I used the Python tokenize module to feed my model, and with excellent parser libraries like Lark[0] out there it wouldn't take that long to build real quality parsers.
Of course I could be totally wrong and they might just be dumping pure text in, shutter.
