I would think that the tractatus would be more useful to an AI. But Witgebstein's remarkable ability to shift the paradign and over extend into a meta level of analysis seems similar to the way alpha mind and Leela play chess. The tools W uses to understand perception have a more probabilistic and irrational nature then the tools he uses in his previous work. As if he realized that human communication cannot be considered as a closed and finite system, hence I cannot see how his ideas are implemented in these applications, yet.

Yes, and considering the Tractatus as a framework for a closed and finite set of linguistic rules, such as a domain specific language has great applicability.

For example, I flipped open my copy (yes I keep a copy on my desk) and opened to 4.122: rules to indicate internal and external relations between objects. Almost reads like a system requirements document.

A conception of language he famously threw out in the Philosophical Investigations!

Yes, because humans don't operate in a limited, context explicit vocabulary. But your point doesn't destroy the value of Tractatus to be used for another purpose.
