"Paul's core argument (which I initially missed) was that popularity is
never a good reason to do anything, especially if you're trying to innovate.
If you do it how most people do it you're more likely to get what most
people get -- mediocrity."

True, modulo programmer talent.  But programmer talent varies by an order of
magnitude. So it still comes down to programmer ability, mainly.

And ability to do what, exactly, in software?  Most work in software is
still where it's been since the 1960s: in maintenance of existing systems.
 If a large Java system has a bug, you're not going to fix it in Ruby.  If a
large PHP/MySql system needs a modest new feature, you're not going add it
in Erlang.

There are times when you should question popularity, and Paul Graham's essay
makes a good case that people don't question it enough, at those times --
and that, because of that, if you do question it, at those times, you can
win.  But when you're maintaining a large, sprawling, legacy system, you're
not doing it in that system's (main) language because the language is
popular -- I've even had to do maintenance in Fortran, a language that, as
far as I can tell, was unpopular almost the day it was born.  No, you're
doing it because to do otherwise is either impossible or so awkward at the
interfaces as to not be worth it, and/or because you're asking other
programmers to learn and like the new language you choose even when it is
possible to incrementally change the code base in the new language, and/or
because to start rewriting the system from scratch is nowhere near an
option, financially, for the profit-making (you hope) entity you work for.

This is an aspect of the software profession that I suspect Paul Graham, for
all his other deep insights, has never really been exposed to, and which he
doesn't really understand at the level of migraine headaches, unlike most
programmers.  Near as I can make out from his own bio, he went from CS grad
school to art school to writing Viaweb from scratch in Lisp to cashing out
big-time from the Yahoo! acquisition of Viaweb to becoming a VC.  Nice work
(and play) if you can get it.
