And...it's a good plan. There's two cooling problems, pulling heat off the wafer (water cooled loop or immersion cooling, this is easy) and dumping the heat somewhere. The second part is why the place being cool matters, I imagine a big radiator on the roof. Could also dump the heat into a river if it's chill.

You and I have real different meters for "easy", George.

Everything is easy if you don't have to actually go through with your plan

How do these goals set out the needed ratios of memory to compute to interconnect bandwidth?

An ideal machine designed to train GPT4 in a day is likely very different to the ideal machine to train 50 GPT4s as once over a few weeks, which is very different from the ideal machine to train a model 100x bigger than GPT4 (perhaps the most interesting).

You're not describing bipolar disorder, you're describing symptoms of schizophrenia. Schizophrenia (and other similar disorders) affects your ability to think and behave coherently. It's a detachment from reality. Bipolar disorder is characterized by long (weeks or months) mood swings that range from very motivated and often positive to deeply depressed. When you're "up" you feel overconfident, impulsive, and restles…

You've gone too far in the other direction. Mania can be extreme, far beyond what an ordinary person could imagine "very motivated" to mean. Deeply irrational grandiose thinking is common. Either mania or depression can involve psychosis, hallucination, or catatonia.

> mania or depression can involve psychosis, hallucination, or catatonia

Sure. And diarrhea is a possible symptom of the flu, yet saying "I don't have the flu, I'm not shitting my pants" is just outright wrong. Saying that people with bipolar disorder think their a god and see symbols and signs is like saying that people having a stroke are characterized by vomiting and stumbling around.

Wyoming seems like a good place to build such a thing.

How is the sun there for the solar part?

~220 sunny days per year apparently. Plus there's plenty of space for wind energy.

NCAR has a supercomputing center there: https://en.m.wikipedia.org/wiki/NCAR-Wyoming_Supercomputing_...
