So... 1-2 orders of magnitude smaller than a human brain. From Wikipedia:
> One estimate puts the human brain at about 100 billion (10^11) neurons and 100 trillion (10^14) synapses

Assuming linear scaling, that would put an actual simulated second of human brain neural activity somewhere between 6 hours and 2 days.
- higherpurpose 13y agoIf it's 2 days that puts us about 26 years (2040) away, compared to the original assumption, which would put us 16 years away (2030), assuming "Moore's Law" continues to happen every 18 months (regardless of whether we'll be able to double the number of transistors per same amount of space anymore or not).
