There was once a discussion about reading programming books and similar point was made about learning on the go. One HN'er pointed out that reading end to end helps to know what all exists. It resonated strongly with me and since then, when I start on a new topic - I make sure to read at least one book end to end.
But if it is your job to use photoshop on a daily basis it's worth going deep into that tome.
It made me chuckle. When I was a kid, I lived in a country aligned politically and culturally with the Soviet Union (it was a while ago). At school, we were taught the Russo-centric version of history. As the USSR collapsed, the country westernized, and we were taught the West-centric version of history. At least one of the two versions was undoubtedly full of fiction.
Recently more and more academics have started talking about bias in history, particularly cultural. Most cultures seem to exaggerate their history and gloss over some blunders to some extent.
Here's an interesting video example of cultural bias in history - https://www.youtube.com/watch?v=py1ZY0xGkNo. Here's an interesting book with a different take on cultural history - https://www.amazon.co.uk/Peoples-History-World-Stone-Millenn.... And, if I remember correctly, Great Courses Plus had a World history audiobook that specifically focused on the history of the rest of the world as opposed to the Western-centric variant.
Random tangent - over.
When I see a 1000 page tome about every single feature of Photoshop, then nope. I'll google it thanks.
History is non-fiction, too. And I'd definitely rather read a book than some blog, because there will be a long thread of things that build up on each other, and I think books are just better suited for that.
So, things that require prolonged attention because of an overarching concept I'd rather read about in a book.
