I think people underestimate the power of IoT and automation to make independent living possible much longer. I recently installed the basics of my home automation system at my grandma's. Her keeping her thermostat set reasonably was an issue, and I've got the smoke detector on the system as well.
One of the things I'd like to add is the ability to detect natural gas: She doesn't have a lot of gas appliances, but she has no sense of smell, so the usual warning sign for natural gas she'd never notice.
