> Determining the meaning of a sentence is a problem where the real answer depends on observer dependent perspective and therefore will need a completely different way to measure success compared to more 'mathematical' tasks like Go. Trying to program a machine to account for this kind of personal experience that humans have, as well as for individual differences between people will be quite challenging I think. I also think that the most significant advances will come from cross cutting academic disciplines like Psychology, Linguistics, and Philosophy of Language. I have worked off-and-on on a project to detect metaphors and identify the concrete meaning the metaphor is attempting to convey. Amongst many other things that project taught me that it is nearly impossible to get more than five linguists to agree on what a metaphor is in the first place.
