It depends a lot on which parts of education you're talking about. The first 9-12 years are required so that kids have something to do while their parents are at work. Learning stuff and interacting with other people is a nice way to spend their time.

From that point, it depends on the subject you decide to study. It seems to me that medicine students get a lot of real life practice during their training, which makes the school almost irreplaceable.

In other areas, like programming, you're better of staying at home and watching online lectures and making your own pet projects to learn, as long as you have enough self discipline to keep yourself on track. There are tons of resources you can learn from and you can practice as much as you want. I did it and it has been working well so far.

Overall, I wouldn't say we should ditch education at all, but we should seriously rethink the way it works. We can do much better than this.
