I am a big believer is what he is doing. I worked both in financial firm and now have my own small factory. There is so much wast in financial firms. in the early 1990s, people with MBA where getting 100k a year for just doing spreadsheets. On top of that, it is not a full days worth of work. the work was not rewarding and it was high stress. The paycheck was great, for sure. I am trying to do that same thing now with my small manufacturing shop. Ordering of raw materials, Manufacturing allocation, labor etc are all controlled by a software. These are all boring jobs that an AI will do a much better job at.
