A bit off topic, but worth keeping as reference when someone 
complains about the GC,

John Carmack's answer regarding how he sees GC question on the 
Lex Fridman Podcast.

"It is only when you get into the tighest of the real time things 
that you start saying, no the GC is more cost than it has 
benefits for, but that is not 99.9+% of all software in the 
world..."

He eventually follows up with a discussion he had about the 
matter on Twitter, and how some developers cannot let go of the 
good old days fighting for each byte.

He might know a thing or two about high performance code.

Maybe an interview to bookmark and post on the regular GC 
discussion threads, as pinned answer.
