One other reason IoT sucks, companies can just disable a perfectly fine device whenever they want. Or sometimes not even on porpoise, like when the company just goes bankrupt and your "smart" scale doesn't work anymore because the api is down.

I won't buy any "cloud" garbage, unless they have an open protocol to make it possible to run your own back end WHEN (not if) the company goes tits up, or some middle manager just decides that that particular product doesn't meet the company's "vision" anymore. So many examples of perfectly fine hardware instantly turned into e-waste in this way already. Companies should have to pay huge fines when they pull those stunts.

As the movers are taking the doors off the fridge, I am looking at the top panel they pulled off, and see something that catches my eye. I ask my friend if his fridge was a smart fridge, and he said no. But there it was, a wireless module like you'd see in a laptop. Turns out, there is a higher end model that is "smart," and the company uses the same parts. This panel had a slot for the card to sit it, and rather than not put a card there for the lower end fridge, they put it there. Not sure if it was connected before they pulled the panel off, but even "standard" devices are coming with "smart" technology....

Your comment about cars sounds just like my complaints. My current car while has a nice looking screen, most of the controls, from heating, radio, streaming, etc. are on the screen. If the entertainment system fails, I can't adjust the temperature. My older car, which also had an entertainment system, still had knobs, and I could do most things without having to move my eyes off the road. Now to change the temperature or fan speed i have to look. To make matters worse there are a lot of options that I can do on my smartphone such as starting the car, unlocking the car and and all of this is standard on the car. Sure it's a convenience, but I don't trust it's security, especially when I saw a demonstration years ago on how easy it is to hack a car, and that was before the trend to computer control everything in cars.

18:30, TCP and IP are from the same time period/standard but are different layers, so the TCP header (or UDP) will be enclosed in whatever is implementing IP (ethernet and or wifi), and the TCP header won't have to care about ip/mac address, as that's the layer below's problem. But the OS will pass that info up to the programmer/application as they do care.
