My point was more around him saying that focus on psychological health will be looked back on as one of the worst things to happen for humanity.

Also, I’m certainly not saying sleep the day away, but sleeping until you feel well rested feels pretty obvious. There’s a big difference between getting the minimum amount of sleep to get through a day and getting enough sleep to get through a day with high energy levels (as the author also found).

Also, if you do any sort of intensive working out (as most people should) sleep is an absolutely necessary part of your recovery.
