Vitalik started out years ago with writings consisting entirely of self-citing the Ethereum echo-chamber. Judging by the citations here he's starting to understand the value in the works of the established institutions, tenured university professors, and career cryptographers -- people whom it's obvious in his circles are either loathed as some irrelevant elites or simply, wholly unknown.
Now that Vitalik has spent the last few years actually surveying the last decades of theoretical achievements in the literature, maybe it's time to build a secure distributed world-computer. Oh wait.
