Most outages nowadays are caused by misconfigurations or hacking, not individual data centers going down. Think Azure, AWS, etc.

Renewables aren't a panacea, but they exist now and are seeing growing deployment, even without "fuel sources becoming less plentiful". Too late to prevent climate change, but definitely early enough to prevent widespread power scarcity.

Oh, companies will definitely try, and many people will go along with it. But, people who care will continue to maintain self-hosted projects e.g. Home Assistant. Hardware can be jailbroken, and/or small manufacturers will be willing to charge a premium for open/hackable versions. Worst case, many "smart" items can be cobbled together from Raspberry Pi/ESP32/ESP8266.
