However, in the short term, I think the areas where AI has the potential to make the biggest impact are where we have huge amounts of data (and gathering data is cheap/getting cheaper) and we have an obvious objective. I am really excited to see what Deep Mind will do with their collaboration with the NHS, and I think some incredibly exciting thing will happen when people with a deep understanding of biology collaborate with people who really understand deep learning.
The difficulty is that in industry the people that often have an easy time raising funds are impressive bullshit artists that are great at selling stuff (Theranos, Verily) while in academia people often spend too much time in their own comfortable silos, and straddling multiple fields is a very difficult act to pull off if you want to ever get tenure.
