Those things are a tiny part of the work though and are all about generating boilerplate code. Tons of boilerplate code isn't the hallmark of a great codebase, I don't think many programmers spends more than 10% of their time writing boilerplate code, unless they work at a very dysfunctional org.
It is true it is faster than humans at some tasks, but the remaining tasks were most of the time, you can't gain more than 11% speedup by speeding up 10% of the work.
