This is a solution (evidently imperfect and arguably obsolete) the education system uses to address the problem of proving the fact a student has gained desirable knowedge and experience. It can and should be deprecated altogether once we come up with a better solution to this. And we certainly can. For example, we can invent ana AI which would interview a student/candidate a way, proven (by numerous comparisions to their actual performance measured with other methods) to estimate their level of expertise and capability with sufficient degree of precision.

In case such a new way proves reliable and efficient we can even decouple expertise measurement and actual education on a mass scale then - let people gain knowledge whatever an alternative way they want and can, then just come and pass the test to receive an accredited degree. This way we can automate production of unlimited stream of certified experts.
