What they will do for unwanted data that stored in facebook, twitter, google and etc in 2050? It will contain huge no profiles of people whom are died

technology evolving these days too fast, imagine what will happen after40 years, the demanding storage space will not be an issue in future. in my opinoin it will be so challenging for software engineers at that time to develop more intelligent algorithms to handle this huge data. i think the "virtual social network" will not be enouph to describe facebook or twitter or google plus, it will be centuries of global culture that transfer the concept of life to a virtual life.

Simply, they can delete the accounts which are not used for over10 years.
