ideas where you do something really different on the algorithm scale and get a big payback I think it's not as likely that you'll see that in terms of things like core machine learning technologies like a better classifier or a better reinforcement learning algorithm or a better generative model if I had the gun idea today it would be a lot harder to prove that it was useful than it was back in 2014 because I would need to get it running on something like image net or celibate high resolution you know those take a while to train you couldn't
