Question from a recent CS grad here, who just learnt about CAP: what do you mean by “very poor trade-off thinking in the decade that followed”?

A Critique of the CAP theorem by Martin Kleppmann.

Basically naive CAP theorem assumes "no latency (delay) allowed", in which case, yeah, sure, the quorum must agree or you are writing to a split-brain quorum somehow. But what if delay sensitivity is a knob that can be tuned, and writes have conflict resolution?
Martin Kleppmann's book Designing Data-Intensive Applications is considered a useful tome for anyone who needs a insight in the complexity involved in distributed systems (hint: getting data in ram flushed to an SSD also involves multiple moving parts)
