Hiring a software engineer in their late 40s:
* Understands your stack better than you do after glancing through the repo for five minutes.
* Will rewrite said stack 2x as fast, and half as buggy if you let them.
* Gives zero fucks.
* Knows we're not *really* like family here.
* No, seriously, absolutely zero fucks given.
Do not cite the deep magic to me, product manager, I was there when it was written.
