But Knuth did an excellent job in writing down basic algorithms. And without those the other "inventions" would not been possible. I am also not sure, if Knuth himself invented some basic algorithms for which he does not get credit, because they are not patented. Guess, what would have been happened, when he had patented Tex. I am not sure, if not some of our todays software would be infringing. This is not a mindless down-vote, but I must shake my head, about your ignorance.
