It's understandable but unfortunate that he had so little to say about them. We could really use the wisdom of true old timers in these matters.

I actually found it really reassuring and a little enlightening that he had so little to say about those technologies. I find it very easy to get sucked into a technology vortex (especially on Hacker News), where the imposter syndrome creeps in and you feel like a failure for not knowing some trendy technology that “everyone knows, duh!”. The next time I feel like that, I’m going to remind myself that Brian Kernighan doesn’t know Nix, only used Rust once (and didn’t like it) and doesn’t even know what Linux distro he uses. And no one would ever accuse him of being an imposter or a failure!
