In the future, we’ll all go through “temporal events” every twenty years or so. Everything from the previous two decades will be old/obsolete/out of style/hopelessly old fashioned. “Virtual Bonfires” will consume anything remaining of the previous twenty years.
By everything, I mean everything. Credentials (like an M.D. or C.P.A.) will no longer be valid. An M.D. will be able to practice for a total of twenty years, including time spent in medical school, then their know-how will be dangerously out of date and they will be forced to retire at about forty.
Anybody who attempts to “keep up” will be seen as highly suspicious. Most people over forty will be seen as useless to the economy. However, a “safety net” will keep all the old-timers from becoming destitute.
People who work in fast-food or something equally challenging will face exactly the same thing. Don’t think they’ll escape it by being “unskilled.” Even burger flipping will become completely foreign every few years. I don’t put the “twenty year” limit on there because I think that will be how long it will take for new information to replace the old. That should happen in less than ten years. Twenty years is the amount of time it will take for any person to be so out of touch that they are no longer an asset to their profession/employer/whatever.
Being “current” will be something that only the young will experience, but they’ll experience it for only a short time. People will out-live their ability to adapt. Most of us will be long past our expiration date when we finally expire.
