The answer, I think, lies at the center of the hacker mindset: there is inherent value in the experience of making things, and inextricably, the experience of learning how to make them, regardless of the value of the end product. Surely if we believe it's valuable in and of itself to eg. write a Brainfuck compiler or scrape HN for sentiment analysis or build and launch a satellite with the sole purpose of detecting gravitational waves, we must believe it's also valuable for someone to learn to program and build a project, even badly.

So with that in mind, I absolutely think accessibility is important, resume bullet points and job prospects aside; for the same reason I think art, music and woodshop should be taught in schools even though most kids won't grow up to be painters, singers or woodworkers.
