"TDT is very much a partial solution, a solution-fragment rather than anything complete. After all, if you had the complete decision process, you could run it as an AI, and I'd be coding it up right now."

I must nitpick here:

First you say TDT is an unfinished solution, but from all the stuff that you have posted there is no evidence that TDT is anything more than a vague idea; is this the case? If not could you post some math and example problems for TDT.

Second, I hope this was said in haste not in complete seriousness that if TDT was complete you could run it as an AI and you'd be coding. So does this mean that you believe that TDT is all that is required for the theory end of AI? Or are you stating that the other hard problems such as learning; sensory input and recognition, and knowledge representation are all solved for your AI? If this be the case I would love to see a post on that.

Thanks
