I think Daniel Stenberg's (of cURL fame) journey with AI reports is going to be repeated for every major project and many will not enjoy being subjected to it.
I read 2 or 3 books at once. I pick the one that fits my mood or my activity -- for example, I'll listen to a low effort audio book when out for a walk or when at the gym.

Shouldn't the compilers be on the bleeding edge of the standards? What is the downside of switching to the newest standard when it's properly supported?
It's the type of dog fooding they should be doing! It's one reason why people care so much about self-hosted compilers, it's a demonstration of maturity of the language/compiler.
