And they own Youtube... That will be a massive benefit when it comes to training AI-powered robots I think. Conceivably, an AI that's seen every plumbing-related video on Youtube would be superior to any human plumber you can imagine, assuming a good mapping between the human hand movements in the video and its own robotic arms. And so on for other domains.
It's a scary thought to me that 90% of online videos are hosted on YouTube. If Google were to ever fail, I know that won't happen, but I think the internet would be truly broken if for any reason YouTube is down.
