We do know that there will simply be not enough hands to help the aging people in a way that is personnel. Technology can help a lot but has the risk of creating a too mechanical care. A special lift can help you out of bed but will not talk to you.
That is why I like projects where technology helps us by connecting people and give care in a way that is friendly and personnel. Like this project or this. In the second project my favourite moment was when the elderly lady is told that there is a camera in the Aibo and here reaction is: oh nice, it can see me?
However, today I read that there are even bigger problems in an aging world. In Japan people that turn 100 receive a special silver cup. Only there are so many people turning a 100 now that they had to reduce the size of the cup in order to save money! In 1963, the first year they started this program, only a 153 people turned 100. This year a mind boggling 19,769 turned 100!!!
I think this shows in a symbolical way the challenges we will face the future decades. You can read more about it here.
