Yes I completely agree. Yet I insist that it is responsible to clearly deliver that message that the numbers of applications/jobs are NOT at the same magnitude. Personally I've spent many hours on LISP related topic; I enjoyed the time; I recommend it as a low priority interesting topic. Things like develop a working distributed KV store(MIT 6.824), solid 1000+hours on competitive programming, those skill&knowledge are not only beautiful&interesting, but also make a person a better practical problem solver.
