>The fact is that people need interaction with people

That is your intuition, and probably most people's intuition. I think it is based on the fact that non-people have not, until november 2022, been able to have an intelligent, natural conversation with a person.

If you don't think ChatGPT is able to "have an intelligent, natural conversation with a person," here in 2023, I'm not going to argue. If you don't think that ChatGPT or some competitor will be able to do that in 2030, I think you lack imagination (and probably simply lack experience exploring what ChatGPT can actually do today).

But even if you are right, that people need to interact with people, that doesn't mean we need humans to prepare their meals, help them go to the bathroom and bathe (I definitely would prefer a robot to a human for that), get them around, make sure they take their medications, etc. If they need human interaction, what's wrong with the robot caretaker helping them get on video chat with their kids and grandkids, or with other elders who have similar needs for interaction?

I could certainly see an elder community where hundreds of residents have one or two paid humans to run everything, with the robots doing all the unpleasant and tedious stuff. Human interaction is handled not by paid staff, but by other residents.

Remember also that, in a society where most jobs can be done by machines, there are a whole lot more family members that have time to interact with their loved ones, rather than paying someone to come in and pretend to enjoy interacting with a very old person.

What specific thing does a caretaker do that must be a human?
