Scientists took the complete wiring diagram of a fruit fly brain and loaded it into a virtual body and turned it on.

It started walking.
The scary part is that nobody programmed the behaviour, it just emerged from the structure .
A fruit fly has 139,000 neurons.
A human brain has 86 billion.
That gap sounds enormous until you realize closing it is nothing more than engineering problem (something we are very good at)
We just proved you can digitally resurrect a mind from its wiring diagram alone.
But don’t worry it’s only a fly. For now.
