He makes an interesting point. If you're going to have home servers so you own your data, they need to be in something you own and control that's always plugged into power. There's the router, but you usually don't own that. It belongs to the telco or the cable company. A "speaker", i.e. Alexa and friends? Amazon controls that. The TV? That's a slave to the TV maker, Google, or the cable company. The doorbell? That's run by Amazon and the cops. The refrigerator?
Apple used to sell a box, their "Time Capsule", which was a home server. But Apple discontinued that. Apple became so cloud-oriented that their thermostat has to contact an external server to get the outside temperature.
Most people now have no home electronics that isn't a slave to someone else. Where do you put a home server?
