Good points. I think it's indeed his personal vision on how software should be.
The thing is, I completely agree with his points.
Perhaps his point would have been stronger if he qualified it a bit more as how he feels about the whole thing.
I think this is more than just aesthetic. If I understand antirez, he needs that simplicity to be able to pull off what he does. It's not a nice to have, but the most central necessity.
I do feel exactly like him and I don't think simplicity is a matter of aesthetics for me either, it makes all the difference between thriving and floundering.
