I think a lot of it depends upon what sort of interaction it is that is benefitting the visitee.

If they benefit from providing and receiving affection, then I don't think the current bots are quite up to snuff. If the benefit is from the mental activity that draws them into the here and now and has them interacting in a game of fetch, or telling the dog to do tricks, then the current technology can provide a lot of that.

I have a bit more experience than I'd like visiting an Alzheimer's Care Facility. It seems to me that the residents there benefit from being pulled into the "now". An interactive pet of any variety can help ground them in the moment.
