Btw, I don't consider myself an AI expert. I am not sure what "AI expertise" entails, I guess knowing a lot about lots of things that include stuff like stats/ML but also other things, including a ton of engineering. I think an "AI expert" is sort of like "an airplane expert." Airplanes are too big for one person -- you might be an expert on modeling fluids or an expert on jet engines, but not an expert on airplanes.
