Why AI Demand Is Outrunning Compute Supply

Video summary

Gavin Baker tells a16z’s David George AI compute is underbuilt, with sub-year paybacks and orbital data centers ahead.

Gavin Baker tells a16z’s David George he could not find a worsening business metric in July or August, arguing AI demand is accelerating and the winners need not be limited to a few labs: applications, clouds, open source and Nvidia can all benefit. He says compute investments can pay back in under a year, citing Nebius’s estimated 9–10 months, while heavy AI users may number fewer than 10 million today against 1.5 billion knowledge workers. Baker expects supply constraints through 2028 and warns that blocking data centers could raise prices and restrict access; he also argues they bring tax revenue and manufacturing jobs to American towns. The conversation ranges from Grokbot’s rapid productivity gains to SpaceX orbital compute, which he says could launch by 2028 if Starship becomes reusable. They close on Nvidia’s financing and supply-chain edge, and a likely future where companies combine specialized open models with frontier systems.
