Putting aside the questions of (as some comments here have) whether

  * AI is a “fucking dud” (you have to be either highly ignorant or trolling to say this)
  * Altman is a “charlatan” (definitely no but it does look like he has some unsavory personal traits, quite common BTW for people at that level) 
  * the ridiculousness of touting a cancer cure (I guess the post is targeted to the technical hoi polloi, with whom such terminology resonates, but also see protein 3D structure discovery advances)

1. Altman clearly signaling affinity for the Abundance bandwagon with a clear reference right in the title. Post is shorter but has the flavor of Marc Andreessen's "It's Time to Build" post from 2020: https://a16z.com/its-time-to-build/

2. He advances the vision of "creat[ing] a factory that can produce a gigawatt of new AI infrastructure every week". This may be called frighteningly ambitious at a minimum: U.S. annual additions have been ~10-20 GW/year for solar builds (https://www.climatecentral.org/report/solar-and-wind-power-2...)
