I'd argue the opposite. Since no one is catering to them and they're frustrated with all the new technologies they don't understand, the elderly would pay a premium for accessible solutions that bring them value (they're in the stage when they're spending money, not really trying to save).

It's an 'unsexy' problem, and the average young developer/product person can't quite grasp the challenges the elderly have, but it's a significant, severely undeserved market.

If you're (thinking of) working in this space, feel free to shoot me an email and bounce ideas; I've been thinking about this domain for a while.

Personally, I'd target older wealthy folks with the most intuitive UI yet created: people.

Give them a tablet with one big red button, no controls. They press the button, they connected to a real person. They tell the person what to do, it gets done. If the singularity hits before all your customers are dead: fire all your workers and replace them with AI.

If you don't feel like rolling out a custom piece of hardware, maybe you could piggyback on something most elderly people already own: a land-line telephone. Voice only, but probably good enough.

This seems like a good idea, but it would have high labour costs, I would think?

It's also going to cross over into health and social care, therapy and support for lonely seniors almost immediately. Your call center staff are not going to be adequately trained/prepared/certified for that.
