The market is moving to ARM Cortex Ms, in part because of their clean I/O architecture and good SoC support. An M0 with integrated BLE chipset is easily <1$ today at small scale. Extrapolate a few years and to volume of millions between large companies rather than small startups. Software like mBed OS and 6lowpan support helps too.
You or I might not want chips in our light bulbs, but some people will, and so it is part of the Internet landscape we need to keep in mind.
