Prediction text
A mouse will have a full brain uploaded in years, not decades; first human whole-brain emulation also years away | This isn't happening anytime soon just to to anchor expectations appropriately. We don't think we're months away from a mouse or a human. But I think the right way to think about it is at this point it's going to be years not decades before we get to the first mouse and the first human wholeb brain emulations.
Watch events: Neuralink human trial enrollment; first commercial BCI
Verbatim quote
This isn't happening anytime soon just to to anchor expectations appropriately. We don't think we're months away from a mouse or a human. But I think the right way to think about it is at this point it's going to be years not decades before we get to the first mouse and the first human wholeb brain emulations.
