In theory, FLT could be solved by brute force enumeration of proofs until a match to Wiles' is found. In theory, AGI could be solved by coding all the knowledge in LISP. The difference is that 50 years ago people actually expected the latter to work. Some people still believe so. AGI is an engineering and policy problem. We already have small scale neural models of learning, language, vision, and motor control. We currently lack the computing power (10^16 OPS, 10^15 bits) to implement these at human levels, but Moore's law will take care of that. But that is not the hard part of the problem. AGI is a system that eliminates our need to work, to think, and to function in the real world. Its value is USD 10^15, the value of the global economy. Once we have the hardware, we still need to extract 10^18 bits of knowledge from human brains. That is the complexity of the global economy (assuming 10^10 people x 10^9 bits per person x 0.1 fraction consisting of unique job skills). This is far bigger than the internet. The only way to extract this knowledge without new technology like brain scanning is by communication at the rate of 2 bits per second per person. The cheapest option is a system of pervasive surveillance where everything you say and do is public knowledge. AGI is too expensive for any person or group to build or own. It is a vastly improved internet, a communication system so efficient that the world's population starts to look like a single entity, and nobody notices or cares as silicon gradually replaces carbon. -- Matt Mahoney, matmaho...@yahoo.com ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=123753653-47f84b Powered by Listbox: http://www.listbox.com
