Does this mean we are ~216 months away from having 1:1 performance?

#23An ACTUAL simulation of rat brain would be 1000 000x more useful.
And would carry a lot fewer disturbing implications about mistreatment of simulated former neurological patients.

#24If they really were simulating a human brain, that would have some pretty serious moral implications.
I think in the short term, companies that develop these things will behave ethically without any oversight (by making machines "enjoy" what they are doing) because doing something else would be inefficient or counterproductive. Why would you make an expensive thinking machine miserable? Humans that are happy are way more productive - and machines that are based off humans will be as well. In the long term, if and whe…
Ethically? I bet they will kill them thousands of times during development.
Suppose you, at one stage, have a simulation of a brain that isn't quite there; it talks and sees, but it's audio system doesn't work right. What do you do?
Even live debugging to repair it can be controversial (http://en.wikipedia.org/wiki/Cochlear_implant#Criticism_and_...)

#25Earlier quoted context omitted.
Seems like just a large neural network (which could be of coursed used for AI purposes). More detail is here in the original press release: http://www.riken.jp/en/pr/press/2013/20130802_1/
Hmmm... I wonder If we could record the state of an active brain and "run" it in the computer creating sentience. Without getting theological, what would the difference between the brain and the computer be if they were exact copies and functioned in the same way?
That's one of the many subjects of Ghost in the Shell. From [0], let your web-fu walk the path.

I don't know. If you can simulate a brain, you can alter it. And if you can alter it, you can make it artificially happy, or simply remove areas hosting willfulness, sleep, sexuality or independent thought. Won't make them suitable for all tasks, but for some it would be more efficient.
Ethical? That's the question.

Suppose the simulated mind goes insane within a few seconds. Just long enough to solve a captcha, before being restarted...

#28it is still hard pressed to compete with the brain in your head reading this article.
It took K around 40 minutes to simulate just 1 single second of human brain activity, even with all of its performance prowess. The experiment on simulated human brain activity involved 1.73 billion virtual nerve cells that were connected to 10.4 trillion virtual synapses, with every virtual synapse containing 24 bytes of memory.
There's no way the brain in my head could simulate 1.73bn nerve cells in 40 minutes.

Not at all. Simulating your brain != simulating your mind. Don't become a victim of 'neurobollocks'. http://www.newstatesman.com/culture/books/2012/09/your-brain...

Your New Statesman link only talks about pseudoscience and doesn't support your assertion. The mind is an emergent property of the brain. If you can't simulate a mind by simulating a brain, then what in your opinion would it take? Or is it impossible because we all have ineffable souls that the laws of physics mysteriously cannot access?
