There are definitely enough matter on Earth to sustain additional 100k human brains with signal speed 1000m/s instead of 100m/s? I actually can’t imagine how our understanding of physics should be wrong for it to not be possible.
I think you’re using a different sense of the word “possible”. In a simplified physics model, where mass and energy are easily transformed as needed, you can just wave your hands and say “there’s plenty of mass to use for computronium”. That’s not the same as saying “there is an achievable causal path from what we experience now to the world described”.
The only reason why it can be impossible is if the amount of compute needed to run one smart-as-smartest human model is so huge that we need to literally disassemble Earth to run 100000 copies. It’s quite unrealistic reason because similar amout of compute for actual humans fit an actual small cranium.
How do you know that’s possible?

Did you misunderstand my question?
How does the total mass of the Earth or ‘signal speed 1000m/s instead of 100m/s’ demonstrate how you know?

Why is the amount of matter in a human brain relevant?
