Is Charles Dickens worth it? It's a matter of time, taste and purpose (in reading).

I've enjoyed dipping in. Sometimes found it directly useful to work. But the best of his works I read (in full) was the MMIX book that is a literate program of the interpreter. Second to that was the typography book, a total fascinating delight.

In reality there's probably almost no one who reads any volume of TAOCP in full.

The only way to answer your question is probably to start reading and see if you enjoy it. But expect it take some effort.
