AI can be created today - it's just a matter of money. Put a few hundred billion dollars into genetic programming, or cyc, or data sets for a svm and you can build general AI.

There are some things that aren't a matter of money, and I would suggest "true" AI is one of them (i.e. human level general intelligence). I honestly don't think, even if you had $100 billion, anyone would know where to start to build such a beast. It isn't just a case of building sufficiently powerful hardware - I suspect that would be the easy bit. Spend $100 billion on CYC and you would end up with a big interesting database, not a functioning mind.

  I don't agree with that. 1) How did the human brain come about - evolution. So you can get there with genetic programming. How much computer time do you need - maybe $100 billion, maybe $100 trillion, but theoretically it's doable. 2) What is the brain - conventional opinion is that it's a neural network - ie. if you spend enough money as -assemble a million neural network engineers or -create billions of data sets to train against simple learning algorithms you can probably replicate it's "interface" 3) You can also view a human, or at least a human speaking through email, as a database. If you had enough people working on cyc, let's say a million rather than the 20 or so it's usually had, you could get a lot closer, or exceed, human level performance. Imagine you a couple of professors and a handful of grad students. Would they be able to build a skyscraper within 50 years, and do so from scratch, without any prior knowledge of civil engineering, no access to construction labor, and only access to raw materials? Yet that is what AI has been about for 50 years - a handful of people attempt to build something much more complex than a skyscraper. It probably took many trillions of dollars and millions of workers to get to the point where skyscrapers could be built, and each one individually probably costs more than all the money ever spent on AI research.

    Well, some people think that the brain might be doing something deeply weird with quantum level behaviors to create what we call "consciousness", if that is the case (of course a huge if) then it might not be possible to replicate it in any meaningful sense. If you look at artificial neural networks and natural ones there are a lot of differences. Artificial neural networks are useful tools for some kind of problems, not physiological models of what happens in our brains. I can recommend this book if you are interested: http://www.amazon.co.uk/Philosophy-Artificial-Intelligence-Oxford-Readings/dp/0198248547 http://www.amazon.co.uk/Philosophy-Artificial-Intelligence-O...

      If it's not possible to replicate, how is human biology replicating it?
