No?

How much cheaper is electricity because meters report back and you don't have to come and read them one by one. How many times has the garbage truck passed by my street only to see no trash container out to be collected? IoT means making everything intelligent so that we can better coordinate our resource usage. A traffic light that knows when the tram is coming ahead or behind schedule, how many people are on it, how many cars are to queue on the red lights can make a better decision on which one should be prioritized, possibly saving a fair amount of electricity in the process.

Or, perhaps, a carpet that knows it's clean (let's say the kids are off to summer camp) can tell the Roomba it doesn't need to do its thing today.

We don't need it like we didn't need cellphones, smartphones, smart watches, electric cars. For most of my childhood we didn't even need personal computers.
