Wanna receive messages from your dead friends from time to time? Or maybe you would like to keep trolling after you kick the bucket? Well fear not, Eter9's AI will learn your personality and continue posting for you after you die What's interesting is that your 'counterpart' will continue 'liking' and 'following' stuff on your behalf so I wonder if popular people would be able to sell their avatars before they die  
What is it with humans and the desire to live forever
