Yeah, local LLMs are probably an order of magnitude less efficient at a fixed level of "intelligence" if not more.
It occurred to me much later that local machines could become a shared resource of a small co-op. Or it only runs off solar or energy harvested at times of excess generation (too much daytime solar, lots of wind, or overnight when demand naturally drops).
Exploring how to partition inference across many machines and shed load for idle sections of hardware would be a problem that could be solved by a community of smart people like us here
It's also resilience. I can still do AI stuff if the internet goes down.
