You're intentionally conflating scale here to make them seem the same.

An individual reading code on their own time is not the same as ingesting terabytes to train a machine. No matter how much you believe in AI working similar to the human learning (it doesn't), they are not comparable.

Again, the difference between an individual reading code to work for a salary is orders of magnitude different from ingesting terabytes of code so a company can create a new feature. Claiming these things are the same only makes sense if you ignore the massive differences in scale and the differences between how humans and machines learn.
