I agree with you. Being a corporate department head, I've led exactly one project that's had me digging through my DS&A textbook. But it's much more common to need to go beyond the limits of an off-the-shelf deep learning algorithm. Plus many of the cutting edge deep learning advancements have been fairly simple to implement but required serious effort to create, and being able to understand an Arxiv paper can have a direct impact on the job you're currently working on, whereas being able to read all of TAOCP will make you a better coder, but in a more abstract way.
