The amount of education required to enter the workforce is constantly increasing. We are continually replacing jobs at the bottom of the ladder with machines and robots and things and adding new jobs at the top of the ladder. For example, during the industrial revolution, lots of lower level jobs were replaced by machines, but new jobs were created for the designers and repairers of the machines. Or in the new Willy Wonka movie, the one guy has a job screwing on toothpaste caps, gets replaced by a machine, and then gets a job repairing the machine. But obviously reparing the machine takes more skill than just screwing on the tops. Another example is in research. Isaac Newton said, “If I have seen further, it is by standing on the shoulders of giants.” As more and more research is done, there are more and more things one must learn before becoming an “expert” in their area.
Anyway, this all means that it takes more education to be able to enter the workforce. This means two things: you have to study for more time, and you have to become more specialized in what you do. It’s not possible for people to reach this education level in a broad area, so people are becoming more and more specialized. But also the length of education is increasing. Unless education changes, people are going to be going to school longer and becoming even more specialized in the future.
One solution could be when we eventually have computers that can connect directly into the brain. Perhaps we will have the ability to simply download information to the brain and educate ourselves that way. Perhaps we’ll also have the extra computational ability to learn/remember/understand all the things required to become an expert in fields that have been researched for hundreds of years now.
