The irony is that the vim camp can use just the same "argument" here about emacs. So that is a weird comparison to want to make here.

Well, being old does not automatically mean better. Peak human physical performance typically happens, with some exceptions (Justin Gatlin, if we ignore the use of enhancement drugs) in younger years; see Usain Bolt's fastest time achieved when he was young (23 years, in 2009). For mental tasks it is not so limited, but for physical peaks it is often in the younger years. For some software projects it also is the case that older age means more code, which in turn automatically mean smore bugs, all other things being equal. I am not necessarily questioning as to whether emacs has more bugs; my point is that the comparison/analogy does not work as means of quality assessment.
