I am not a coauthor but do know a decent amount about AI systems from a maths and computer science degree from Oxford, couple decades coding and being lead architect on https://hai.stanford.edu/watch-caiac amongst other stuff :)

Originally took a break from being a hedge fund manager to build AI lit review systems to investigate ASD etiology for my son along with neurotransmitter pathway analysis to repurpose medication (with medical oversight) to help ameliorate his more severe symptoms.

Had 100% satisfaction from programmers with some math knowledge trying fast.ai and members of team active there, really nice take off point into a massive sector.

It digs nicely into the principles and is not a surface level course. The stable diffusion one will need some good work to get through.

But yeah my job now is to get billions of dollars into open source AI to make the world happier, happy to do my best and let the smart and diligent folk buidl.
