A lot of people already have. The fact that school voucher systems and charter schools exist in some areas is testament to their heroic effort. However, it is too little and maybe too late.
Definitely too late for kids already in school, but I would wager that humans will be educating their kids in schools for hundreds more years (maybe more). This would be like Edison giving up on the light bulb because it was too late for the kids who had to go to bed at sundown.
