Professor Sipser would have agreed to these words knowing that the first "if" clause, with its "correctly simulates" can never hold. He would have wanted to get you, a crank, off his back so that he could continue uninterrupted with his work. He surely has real students who want to learn, to teach. Agreeing to that vacuous truth, which wouldn't stain his conscience, seems to have been effective. You appear not to have troubled Professor Sipser in over a year. > -- > Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius > hits a target no one else can see."
