Please. You pick a lowest-common-denominator language like Java or Golang so that you have a large pool of cheap, semi-sentient code monkeys to hire from.
If you choose LISP, you're actually going to have to expend a little bit of effort on identifying, recruiting, and retaining actually competent people. That's a problem when you're looking to put butts-in-seats (as is the case in my industry: defense).
That just pushes the problem back a couple of decades. Common-LISP is from 1984, GoLang is from 2007.
In twenty years, Common-LISP with all the advantage it supposedly has couldn't make anything that a 'code monkey' could use? Why not? Is it awful at writing tools?
Or is it that the alledged advantages of Common-LISP don't really make any difference in reality because they are over-hyped or even non-existent?
Note that I'm not saying "why did they pick one language over another", I'm saying "Common LISP can be the best tool for the job - yet they waited twenty years to use a 'worse' tool to implement a 'worse' tool". That doesn't make sense.
