ML has been on IoT devices for years. Heck, there are embedded arm SOCs with built in CNN coprocessors that will run your tensorflow models as-is. Again, they've been shipping in volume IoT products for years.

If ML is a win for an IoT device, the hardware's been there for a while, though I'm sure yet-cheaper hardware might unlock a few more applications, it doesn't feel like much of a game changer.
