Not likely! Storing a single human brain’s connectome (the complete map of all neurons and the interconnections between them) would take half the planet’s digital storage capacity: 1.3 billion terabytes. In other words, to store just a static map of the physical brain structure of two individuals would require 100% of global storage capacity. And that’s just the structure, not counting any actual processing. We only have the roughest idea of what that would require, but last year the world’s 4th most powerful supercomputer took 40 minutes to simulate just 1 second of 1% of a brain’s activity. Clearly, our brains won’t be replaced just yet, or probably any time soon!
