It's a pipe dream to believe that the public education system is going to adapt to be a one-size-fits-allMay I take it that you mean "It's a pipe dream to believe that the public education system is going to adapt to be SOMETHING OTHER THAN a one-size-fits-all"?
As a parent (of four children, two now adults) and as a voter and taxpayer, I am of course interested in general improvements in the education systems of all countries, and especially in the country I now live in, the United States. I think it will be helpful for advocacy of thoughtful improvements in education policy to be aware of how much young people do and can learn, whether or not their schools set high standards. I think setting more ambitious standards will make school less boring and more meaningful for the plurality of young people in the United States, and quite possibly for the majority of young people here.
As a parent, I chose to homeschool my children early on. That seems (according to my oldest son's testimony, sent to me by email) to have been helpful for my oldest son's career as a hacker. My second son may pursue a programming career too, although he has plenty of other interests. I'm still interested in discussions of education policy, the issue that drew me to Hacker News, here because I can still adjust the educational plan for my two younger children some more, and because this matters for all of us, childless or not. But so far I have found it expedient, in a high-income school district with high parental educational levels, to homeschool my children for their elementary education. They then go to the friendly local high school (which has improved its academic standards recently by dint of competition from Minnesota's public school open-enrollment policy) and take lots of AP classes and do lots of academic extracurricular activities with friends who have open-enrolled from the territory of other school districts. It isn't perfect, but it's a trade-off that works well enough for us.
