To be more precise, it was 40m to simulate 1% of the neocortex.
Using Moores law we can postulate that it takes 17 years to increase computational power a thousand fold and 34 years to increase it a million times. So that should give you more intuïtion of what 1% actually means. In the course of a couple decades it would take 4 minutes to simulate 1 second of an entire neocortext (not the entire brain).
That doesn't sound too impressive either, but bear in mind that human brain <> strong AI. We are talking here about the physics model of the human b...
There are many facets to depression and to analyse them from a evolutionary perspective, you should evaluate every single one them separately.
Some specific types of depression, like 'burn-out' syndrome, have an obvious cause-effect and is some sort of defense mechanism to protect you from yourself. The metaphor of getting burned is fitting, because it's similar to physical pain.
But evolution doesn't bother if something is beneficial or not. A common mutation can be devastating for the individuals mental health, but as a species we can have evolved to cir... (read more)
