There are two serious problems with that question. First, why must there be one curriculum? Second, why should anyone but the students decide what they should learn?
Of course I know that these problems are rarely mentioned. We just assume that there should be exactly one course of study in high school and that students should be told what they have to learn. These assumptions are so strongly held that any suggestion by me that school needs a re-design causes people to assume that I want to dictate what the curriculum should be. I don't. What I do want to do is to design as many curricula as possible to allow as much choice as possible. Someone I know told me that his daughter was bored in school and that what she really wanted to learn about was set design. And why shouldn't there be a "set design" curriculum for those who want that?
Since curricula can now be delivered on line, as can teaching, the old excuse -- not enough demand - goes away.
Of course there is another objection too. Such a curriculum wouldn't include the important stuff. Really? What is the important stuff? I am sure that one actually has to know a great about "the important stuff" whatever that is in order to "set design" or anything else that is part of the real world. The place to teach the important stuff is within a context of interest to the student where it would actually be used.
We need to start understanding that our unspoken assumptions about education are wrong. Every high school drop out knows they are wrong.
