I use TAOCP on a regular basis where I work, I started writing DSLs for industrial systems then learned from TAOCP how to optimize memory of these embedded systems. We leaf through the pages whenever we can and always find something relevant to what we're working on. We also used just a few LOC for hand rolled Knuth in a customer app field engineers use to quickly find documentation that is so fast and accurate we get offers to buy it. As a result these corps all keep their ancient embedded systems that would cost multi millions to replace as we keep making them faster and more reliable. Knuth is also a fan of abstracted programming languages like Literate programming which he claims without it he wouldn't have been able to create a lot of the exercises in recent TAOCP volumes so anybody declaring that if you're "just" a Java programmer you won't get any use out of the books are likely incorrect.
