Where did I say that more powerful languages don't give benefits?
Besides, assembly fails the "allows to execute quickly" test.

I'm pretty sure that what PG was trying to say was that given two languages X and Y that if X is more powerful (expressive) than Y it will be better for startups.
Not that if you don't use X there is no way your startup will be successful, and certainly not that if you don't use LISP you won't be successful.
