Watches

Smart ones can be useful. It's nice to be able to check which app a notification came from and get a short preview without having to take your phone out of your pocket, which can also help people who suffer from the classic case of "I picked up my phone to check a notification and now I'm on TikTok"

Light Bulbs

I agree these don't usually need to be smart, but there's also good reasons for them. Changing lights/rooms while you're away so it looks like someone's home, setting them to slowly dim throughout the evening so you more naturally get tired on schedule, and the colors can be nice if you need to theme a space. Good for people who often host parties.

Kitchen appliances

Yeah I got nothing here, make 'em all dumb again 🙏

There is still a lot of good uses of "smart" tech, it's just you'll find most companies would rather cram it in everywhere rather than just where it's most useful. For example, it can be good to have smart appliances like your water heater, if you want it to be able to adjust when it pre-heats water based on when it gets used the most, adjust based on the current cost of energy from the grid and output from home solar, etc.

Can also be good to have in something like a thermostat, or electronically connected blinds. You can have them raise and lower automatically based on the angle of the sun to automatically adjust the temperature in your house before relying on a more costly appliance like a heat pump.

Not all smart tech is bad, it's just that most of it is.
