Training data is the masses of code from everyone.

Restrict that data to just the best of the best, the tersest of the tersest, and we’d see better output. I don’t think people are sharing that kinda stuff (Jane Street’s gems stay locked up), and even if they did my presumption is that it’d be too narrow and demanding for general audiences.

Big hopes for the long future, damned to some degree of mediocrity in the near term mass product.
