You're not a hypocrite because you're wrong, you're a hypocrite because you complain about others "wasting time" while you waste time, it should also be noted in a less constructive way. The fact you're objectively wrong about them wasting time is irrelevant.

Nothing useful was produced, nothing useful was learned in the process. Even if there was some peripheral learning that took place, it was accidental at best.

What are you basing this on? It's just your own assumption. You've gone from "nothing learned" to "the learning doesn't meet some arbitrary standard I've set and apply at random"
