The technical merits of languages just aren't relevant to choosing them for most developers, unless they're helping solve a people problem.
"Artisanal" languages like Lisp, and Forth can be fantastic at solving problems elegantly, but that's not the most important thing to optimize for in big organizations where a large portion of your time is spent reading code written by people you've never met who may not have known what they were doing.
Many of the tools that come from big tech are designed to ease the challenges of organizational scale. Golang enforces uniform styles so that you don't have idiosyncratic teams doing their own things. Bazel is a largely language agnostic build system, with amazing build farm support. Apple and Google have both contributed heavily to sanitizers and standard library hardening in order to detect/eliminate issues without reading the code. Facebook has poured vast resources into automatic static analysis. AWS built an entire organization around treating all their internal interfaces the same as external ones.
