If they have a big enough database of half-typed-then-abandoned questions, do you think it would be possible to train an RNN (or something) to read a post in progress and predict at what point the answer should be obvious to you?
I seem to recall something similar which does pattern matching comparing the code that you're typing with a database of code in accepted stackoverflow answers and gives "smart autocomplete". Not sure how I stand on the overall impact of such a thing but technically it was cool. :)
