The second part I was only half kidding. There could be decent money in making believable propaganda videos. Some are already doing it as a jab to their opponents. My ulterior motive would be to desensitize the general public to all video content and make them wary of believing anything they see. adding a layer of insulation from the media and governments to all people instead of just techies.

Elderly that are not using the latest tech would probably enjoy some reviving old memories and see what could have been. On the other hand it may cause them to become depressed. I guess one would have to try it out with a handful of people and study the outcome. It probably would not be a big money maker since most elderly in care facilities are on fixed incomes but it would be good practice. If this was tried I would be curious to see the outcome regarding what percentage appreciated this vs. were depressed by what could have been vs. where they ended up in life.
