"We did the back-of-napkin math on what ramping up this experiment to the entire brain would cost, and the scale is impossibly large — 1.6 zettabytes of storage costing $50 billion and spanning 140 acres, making it the largest data center on the planet."
Look at what they need to mimic just a fraction of our power.
CERN datacenter has 1600 times less capacity

Although global storage capacity will be 125 times higher by 2025 than whole scan would occupy

I'd be curious about the access speed comparison, because I'd assume for the brain it's be RAM equivalent, not SDD
The brain is a tightly coupled biological computer , it's access speed is practically instantaneous
Also data/processing in the brain is some mighty uncovered field of science
Just gotta lower the clock speed enough for us not to notice. As long as we don’t interact with the outside world, just other stored human brains, it can be slow as molasses and we won’t notice.
