I found it to be not the case. Upon reading the first chapters I started wondering how could this be useful for coding. So I jumped to one of the last chapters where they show you practical applications. Upon reading those I thought: "I can do all this in code just fine without using linear algebra".
I never touched that book again.
About two years ago or so I started to make little games for the pico-8 fantasy console. There's some math involved there but almost always you don't use the math formulas as you would in a text book, for example, for something simple like drawing a straight line or a circle, finding paths, collisions... there are very specific algorithms for that, they don't look anything like a math formula, even if they are derived from those.
Just my point of view.
