Which lesson will you carry with you longer? The time you saw a presentation and the speaker warned against X, or the time that X bit you in the ass and you learned from experience why it’s a bad idea? Much of the detail you’re referring to can absolutely be learned valuably from a presentation, but folks with more experience can grok the lesson and reasons behind it much better. Presentation and book learning absent practical experience leads to things like everything being forced through an OOP lens for example.

I said both together is best. You can glean insight from both. It's not an either/or.
