Well here’s one exaggeration that was pretty obvious to me straight away as a somewhat disinterested observer. In her status on X Anna Goldie says [1] “ AlphaChip was one of the first RL methods deployed to solve a real-world engineering problem”. This seems very clearly untrue- for example here’s a real-world engineering use of reinforcement learning by google AI themselves from 6 years ago [2] which if you use Anna Goldie’s own timeline is 2 years before alphachip.
