I think that machine learning will move out of the cloud and onto devices closer to where it is needed. Moore's law isn't what it used to be so it will likely be a blended environment where heavy processing is done in the cloud and then synced to local devices for lighter processing. Things like self driving cars will need more powerful AI without the delay of contacting the cloud. Also things like smart switches, appliances, and such will need some smarts locally, maybe built into some home based brain that syncs with the cloud.
