I would add for practical skills (including some research!) videos and podcasts seem to offer more feedback. Nobody in a book ever tells me what a flange or spline or baulk ring actually is, nobody in a video does either, but in the latter I get to see it and make my own, usually fit-for-current-purpose, inferences.

Closer personal example: I spent weeks trying to bully a supervised machine learning approach into a reinforcement learning one, because the 800-page reference book I used (that claims to cover all machine learning, and is well regarded!) in no way acknowledges the existence of this sub field. For whatever reason, and across multiple fields, I've never found static text to be good at "here's what you should be looking for", and I don't think it's reasonable to discount that knowledge as being valuable.

I've long since come the the conclusion that most 800-page texts are terrible.

Nearly all very-large-texts I've read on technical subjects are poorly written. The early and later sections seem to have little relation to each other; Some parts will be too general and other parts too vague. It's like the author totally loses perspective.

There's a sweet spot of around 250 A5 pages where a subject can maintain consistent scope and have meaningful relationships between chapters.

There are exceptions, but they are few.
