It's kind of like copying and pasting code from StackOverflow.. Except the code hasn't had as many eyes looking at it as something that was pasted on StackOverflow, and it has a higher likelihood of seeming like a correct solution to your specific use case.

Honestly, it seems pretty dangerous. Seemingly correct code generated by a neural network that we think probably understands your code but may not. Easy to just autocomplete everything, accept the code as valid because it compiles, and discover problems at run-time.
