      I am now watching a 6 minute YouTube video on Wittgenstein. Let me know if you have any questions about the man or his philosophy. I will be happy to answer them.

      What's his Philosophy (in simple language)?

      1. We use language as a means to create pictures in the minds of others, and errors in communication are due to mismatch in the pictures. (Tractatus Logico-Philosophicus)

      2. We use language as a "tool" for specific "games" we are playing. Errors occur when others fail to see what is the game. (Philosophical Investigations)

      My take: Computer science people almost intuitively understand this. Which is why they invented precision in the way things need to be communicated. Because things from the work of people like Wittgenstein and Derrida percolated into our discipline.

      I don't know. I think we were more obsessed with ambiguity after our earlier attempts at self-modifying code put us in lots of trouble. We just couldn't keep track of all things. Same thing is happening with AI now. We don't like a piece of code if we can't predict its behaviour.

      Probably time to ask @Plinz about his insights. The question is: Why do ppl in computer science have well defined communication protocols.

      Wittgenstein tried to invent computer science in the Tractatus. He got very far and even knew that you can do everything with NAND gates!

      You mean he did all the binary logic? Nand gates was a pretty difficult thing for me. I never understood during my ug days why we needed to study and, or, not if Nand can do all three.

      The Church Turing thesis is the insight that Boolean logic, Lambda calculus (Lisp), Turing machine and whatever all have exactly the same power. And our computers are built completely from NOT-AND gates.

          You can make all Boolean logic just using NAND. NOT a = a NAND a. a AND b = NOT (a NAND b) a OR b = (NOT a) NAND (NOT b) etc. (if I just got it right before falling asleep)

          This is too much boolean algebra for me, even when I am wide awake.

          Another way of saying this is anything that can in principle be computed with pencil and paper can, can be computed by some Turing machine. If a function is computable, then there exists a Turing machine for it.

          And vice versa, but only if there is no limit on your time and paper. Even more fascinating, it can all done by a sequence of mappings between natural numbers.
