Xor also has another interesting property. If you take a variable and xor it with some value, then xor it again with that same value, you get back the original variable. This makes it useful for encryption. It was also used a lot during the early days for crude graphics manipulation. All operators were used in 1s and 2s compliment integer math, logical reductions ( Karnaugh maps) and face it... digital computers, as they exist today, are composed of millions to billions of individual logic gates (and, or, nand, nor, xor, xnor). Bit level math used to be the 1st item in the computer science curriculum. The fact that it is now only mentioned as a kind of obscure side note kinda gives you an indication of far down the abstraction rabbit hole we have traveled.
I don't feel smart for immediately commenting before watching the video but could you do a video on a chatbot that could hold conversation and seem a bit more intelligent. I understand if not, that would be hard, no?
