A Brief Introduction to Computing Technologies: Crypto, Al, Quantum --- Most discussions of modern tech are either vague pie-in-the-sky ballads or insanely technical. What MBAs need is a sound mathematical and intuitive understanding of modern tech, not so that they can become coders, but so that they can interact with coders and noncoders alike with confidence. The course will involve nothing more than grade school level math, for that is sufficient to deeply understand modern tech and accurately assess business opportunities. The course will last for two weeks and have four sessions, for that is all that is needed to get there.
