I will be the last person to not have a smart home. There will be a banner over the doorway: “Welcome to Stupid House”.

There will be a small cover charge.

You can have a privacy-first smart home. I have. I run Home Assistant in a docker container. No external services/plugins. My smart doorbell streams to my local nvr. If my internet is down, everything keeps working. And it's not even that hard anymore. It's become a lot easier over the last 2-3 years. Still not for non-techie users, but a lot better.
