There are at least two sides to this. On the one hand it could be seen as sad. Sad because why aren't there any humans who can take of her? On the other hand, it's a blessing. Grandma has a companion who she can interact with, who can help her with remembering stuff. Personally, I think the 'sad' part is sometimes unavoidable. Not every elderly has family or family who live closeby. Also, in many countries in the West at least, but also in Japan for example, there simply aren't enough people to take care of other people. So, we have to find solutions for the simple tasks first. Like helping take medication on time, help with cooking etc. Also, a lot of people bond with things almost as easy as with people. Just remember the soft toy animals you had as a child and the dread you felt when you misplaced it. Many people still have those animals in their beds... This is not to say that robots are *the* solution that will make human care unnecessary. But it can certainly be very helpful to ease the workload of caretakers.
