Does anyone know what his NewSQL critique was? (The "“NewSQL” is misguided" slide. BTW, I've read the released chapters of his _Big Data_ book, so I know a fair bit of the slides' context.)
NewSQL inherits mutability and the conflation of data and queries. It's no longer 1980, and we now have the capability of cheaply storing massive amounts of data. So we should use that capability to build better systems that fix the complexity problems of the past.
