these things constitute public goods that benefit the individual regardless of participation.
No chance they're going to take risks to share that hardware with anyone given what it does.
The scaled down version of El Capitan is used for non-classified workloads, some of which are proprietary, like drug simulation. It is called Tuolumne. Not long ago, it was nevertheless still a top ten supercomputer.
Like OP, I also don't see why a government supercomputer does it better than hyperscalers, coreweave, neoclouds, et al, who have put in a ton of capital as even compared to government. For loads where institutional continuity is extremely important, like weather -- and maybe one day, a public LLM model or three -- maybe. But we're not there yet, and there's so much competition in LLM infrastructure that it's quite likely some of these entrants will be bag holders, not a world of juicy margins at all...rather, playing chicken with negative gross margins.
Uncanny really.
What is the justification for considering data centers capable of running LLMs to be a public good?
There are many counter examples of things many people use but are still private. Clothing stores, restaurants and grocery stores, farms, home appliance factories, cell phone factories, laundromats and more.
Why not an LLM datacenter if it also offers information? You could say it's the public library of the future maybe.
Data centers clearly can exist without being owned by the public.
This is not at all true of generative AI.
Why would you want my money to be used to build datacenter that won’t benefit me ? I might use a LLM once a month, many people never use it.
Let the one who use it pay for it.
