There is no reason for a "computer" to do all that and if it could it would not - all that he talked about is about dealing with the limitations of our brains - our mind the machine would not care because it would not care about its limits - we are as a computer one big limited system constrained by the process that brought us into being - chance and natural selection. An ai is not constrained by this anymore than a dog is constrained from finding the same thing funny. humor is not a problem for us because we are part of the problem - we are a constantly derived huge word puzzle. an AI would not be that - AI would have a purpose.
