I've been dabbling in AI recently, and I keep seeing FB's name appear all over the place. They were associated with some work that wrote human readable instructions on how to cook something- given only a list of ingredients. I have no idea why they are interested in cooking, but there logo was watermarked on every page of the deck. I've also read how they are building a really big and fast computer cluster to do ML. I don't know what they are doing on it, but they probably doing some R and some D.

So, yeah, I have FB on my list of innovators.
