I think that attitude is (very) slowly changing though and might not be the default forever.

My elderly parents have asked me about "local backups" of their cloud stuff, their Facebook history etc..

If they're thinking about the risks/tradeoffs of being in the cloud..

I think people use the cloud because there's no better/easier option today.

But at some point there might be. A home appliance (which may be similar to a homelab under the hood but the user experience is where things change) that provides a bunch of automation and home services could be quite attractive if it got to a point of being very turnkey for the average family.

Just like a TV or a gaming console is today.

There’s no better option today because it’s impossible to make it a better experience. That machine at home will need upgrades, it could fail, it costs thousands, it sucks lots of power. There is no mass market appeal.
