i agree with most of this, but i think that > When it comes to knowledge, classes are useless IMHO. i have to disagree. it's a pretty reasonable statement in intro and intermediate level classes, but in advanced classes, a lot of the material covered does not exist in textbooks yet. the info is possibly located in academic papers, or maybe the result of unpublished research. even if the information theoretically exist in papers, it is very nontrivial to find the papers (typically only universities have subscriptions to the journals they appear in), determine which ones to read (just because its published doesn't mean its good, or even true), and then assemble that into a reasonable narrative.
