His comments are provably false. There are countless scientific studies showing the benefits of various strategies for increasing productivity as well as increasing your enjoyment of your work. (e.g. how to make masturbation feel better, how to make programming more addictive, how to enjoy yourself while doing the dishes, etc etc)

He even suggests time-boxing, a very popular strategy for countering procrastination.

Suffice to say, he is yet another unqualified non-expert giving opinions on stuff he doesn't know anything about.
