I am far from innocent here but I'm gonna say no. You are saying IoT is far from a worthy cause. Really? Is it not worthy that my aging grandparents can open the door from their bed and not have to go downstairs, turn on their lights in the dead of night from their phone so they don't have to risk stumbling and falling when reaching for the light switch, or even just more accurate track their health? I think those are all pretty worthy causes.
Also with old people you'd want the tech to be familiar to them so that you don't have to video call them to show them how to reset the WiFi.
And if you're talking about old people who cannot even walk without stumbling their memory would be so far gone that they'd forget how to operate half the devices half the time.
Maybe it would be more helpful to future old people such as ourselves, but I think simpler, robust, and familiar tech is better for old people.
Just another perspective.
It solves a real problem for me, and I think many others too!
