How Much of Your Time Is Expended on Machine Learning Technologies?

I used to spend much more time on developing entirely new technologies, and theni i moved more and more into the application space. And fundamentally, what i believe is that there's kind of a 70 20 an kind of breakdown that i think works really well. About 20 % of things are places where you feel like it's much more speculative and that real technical innovation will be required. There's something that you're chasing, that you think that you might get to.
