DARPA's IBM-Led Neural Network Project Seeks To Imitate Brain
An anonymous reader writes "According to an article in the BBC, IBM will lead an ambitious DARPA-funded project in 'cognitive computing.' According to Dharmendra Modha, the lead scientist on the project, '[t]he key idea of cognitive computing is to engineer mind-like intelligent machines by reverse engineering the structure, dynamics, function and behaviour of the brain.' The article continues, 'IBM will join five US universities in an ambitious effort to integrate what is known from real biological systems with the results of supercomputer simulations of neurons. The team will then aim to produce for the first time an electronic system that behaves as the simulations do. The longer-term goal is to create a system with the level of complexity of a cat's brain.'"
Sorry, had to go for the obligatory Terminator reference. Seriously, the organic brain is evolved, not designed. That means by definition it must be self contained . Self contained means it has to have a ton of backup, self-repair, and maintance systems. Simulatneously, being organic it competes against other organics, so does not have the same accuracy requirements. Close enough is good enough. As such, I don't see how duplicating an organic brain is useful. We don't need what it does, but do need what it does not have. OK, the ability to approximate is very usefull, but I think a direct attempt at that would work better than the indirect.

I see some big issues with this.
You can mimic biology and may end up with a semi-intelligent result. Mimic it well enough, and you may have a fully-intelligent result. But because you don't UNDERSTAND what you built, you can't CHANGE it.
Remember the rules of AI, introduced in Sci-Fi? How would you implement rules like that? You CAN'T implement them if you don't know HOW to implement them. If you don't UNDERSTAND the system that you have built, you can't know how to tweak it!
Furthermore, how would you prevent things like boredom, impatience, selfishness, solipsism, and the many other cognitive ills that would be unsuited to a mechanical servant?
The biggest problem is if people productize the AI before it is understood and suitably 'tweaked'. Then our digital maid might subvert the family, kill the dog, and run away with the neighbor's butler robot, because in its mind, that is a perfectly reasonable thing to do!
Simulations are great. Hardware implementations of those experiments are great. Hopefully, in the process, they will learn to understand how the things that they built WORK. But I pray that those doing this work, or looking at it, don't start salivating about ways to make a buck off of it before it is ready to be leveraged. The consequences could be far more dire than just a miscreant maid.
