People don't pop out old and lonely out of thin air. Don't you think that there were several real people who tried to help him and deal with him during this person's life? It is naïve to think that AI will make any beneficial difference. If these old folks won't listen or take advice from real people, they won't listen to a computer. Everybody reaches a certain age in life where they will be completely set in their ways and never change. For some it comes earlier or later in life.
