OK, you are right. You can type the same query twice. Or if you live long enough you can do it the hard way. But you won't. >Are you now conceding that it is not true that "Models that are simple enough >to debug are too simple to scale."? OK, you are right again. Plain text is a simple way to represent knowledge. I can search and edit terabytes of it. But this is not the point I wanted to make. I am sure I expressed it badly. The point is there are two parts to AGI, a learning algorithm and a knowledge base. The learning algorithm has low complexity. You can debug it, meaning you can examine the internals to test it and verify it is working the way you want. The knowledge base has high complexity. You can't debug it. You can examine it and edit it but you can't verify its correctness. An AGI with a correct learning algorithm might still behave badly. You can't examine the knowledge base to find out why. You can't manipulate the knowledge base data to fix it. At least you can't do these things any better than manipulating the inputs and observing the outputs. The reason is that the knowledge base is too complex. In theory you could do these things if you lived long enough, but you won't. For practical purposes, the AGI knowledge base is a black box. You need to design your goals, learning algorithm, data set and test program with this in mind. Trying to build transparency into the data structure would be pointless. Information theory forbids it. Opacity is not advantagous or desirable. It is just unavoidable. I am sure I won't convince you, so maybe you have a different explanation why 50 years of building structured knowledge bases has not worked, and what you think can be done about it? And Google DOES keep the searchable part of the Internet in memory http://blog.topix.net/archives/000011.html because they have enough hardware to do it. http://en.wikipedia.org/wiki/Supercomputer#Quasi-supercomputing -- Matt Mahoney, [EMAIL PROTECTED] ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=303
