Yeah it's kind of funny that there was a "controversy" in the very FIRST YC batch, when Reddit switched from Lisp to Python (~15 years ago!)
And there was data that showed that like 90%+ of YC startups use either Ruby (often Rails) and Python, including all the most valuable ones like AirBNB, Stripe, Doordash, etc.
So basically it's been 15 years since Ruby and Python have been acceptable (or even better) Lisps, according to PG's own metrics.
Ruby and Python both have garbage collection, REPLs, and enough reflection/metaprogramming to "compress" your code.
