Devices having cellular modems isn't something new. Many cars already ship with them, for various purposes. WiFi will likely remain in use with smart TVs for a while as video content is data intensive so not really well suited for cellular, but likely stuff like your dishwasher or your stove might include cellular modems in the near future. The data they transmit is limited and you make setup easier as you don't have to type in a WiFi password any more.

Difference between a car & a dishwasher is that a car is typically outside (at least during use) which would help it to get a signal.

Anecdotally inside my house, phones generally get no/weak cell service but WiFi is accessible anywhere in the house.

Obviously they could include both, but if it were relying only on cellular, my washing machine quite possibly couldn't get a connection

Carriers run IoT-specific networks[1], which are optimized for use cases such as telematics (low power consumption, low bandwidth usage, but high penetration and coverage). So it's entirely likely that your washing machine would be able to happily send along telematic data via the same carrier your cell phone can't even establish a connection to.

Baseband not for video streaming, but just for telemetry. I mean, this is a thing: https://www.twilio.com/docs/iot/supersim/getting-started-sup...
