It is learning though. It’s not just copying the code.

Code gets turned into tokens and then it learns the next most likely token.

The issue that I see most people talk about it the scale at which is learnt.

A human will learn from other people’s code but not from every persons code.

Copy/pasting at scale is how tons of software has been written for a long time, or have we all forgotten the jokes people used to make about StackOverflow?
