Hacker News Reader

Regarding sleep: I wondered recently if Matthew Walker responded to the critique from here: https://news.ycombinator.com/item?id=21546850

He's certainly responded to a lot of reader critique on his blog: https://sleepdiplomat.wordpress.com/2019/12/19/why-we-sleep-...

Not sure if that covers all of it, and I'm not sure whether any of it is factually correct.
