There was nothing in the article about robots or AI, OK? Maybe that's what you like, but this article isn't about that.
Current estimates are that ~6M people in the US have dementia today, out of a population of ~340M. Let's call that about 2%. Immediately obvious conclusion: There is not shortage of population to serve as caregivers.
What there is a shortage of is anyone who would actually want to work in a US dementia care facility. It's one of the lowest paid, least appreciated and most grueling occupations. Emotionally grueling as well as physically. How many 80 year old's butts did you wipe on Zoom today?
In spite of this, most staff I encountered were dedicated to the residents.
Maybe you're ready to lock your senile parents in a room with a robot dog, but I'm here to tell you that the human interaction is one of the only decent things in US assisted living. This is 100% from the people n the trenches. Healthcare ownership are bloodsucking jackals. Once you remove that person to person contact, the only thing left is ownership exploiting the defenseless.
