I think people just stopped using the buzzword IoT/Internet of Things even though there are many more devices in use now than before. Just a few years ago Amazon echo was just a curiosity, and now connected speakers are everywhere. I have 70+ smart switches and outlets in my house, and even my hot tub has internet connected sensors measuring water quality. Nearly all of my neighbors have a smart doorbell, internet camera, or smart lock. And these are just the obvious examples. Self driving cars are loaded with sensors that send data back to the mothership all day long. I'm not sure of the dollar amount to put on all of that, but IoT is alive and kicking.
