There is nothing wrong with walking or riding horses to get to where you need to go but I wouldn't celebrate that. It's a nice hobby bit not efficient. The same will probably happen to most of "human made code". It's fun but doesn't make much sense economically.
I enjoy pressing keys and entering code; I find it to be the most efficient way to communicate with my computer. Why would I not spend my time doing something I enjoy?
I thought you were talking about economic efficiency, not maximizing enjoyment. You can do anything you want with your time if you're not worried about economics, but that sort of contradicts your original statement.
