> No one teaches these languages. How popular could they get if companies and universities spent millions of hours collectively drilling even the most marginal programmer on how to use them like they do for C++ and Java?

Schools and universities have been teaching Pascal/Lisp/Caml/Scheme for decades, yet (almost) nobody used those languages to produce actual software, neither as a job nor for free software side projects; and a majority of jobs implied the use of a member of the large C family (or VB at the time).
