There&#x27;s an old deep division between people who think everyone ought to learn the depths of a computer and people who think that&#x27;s unreasonable and maybe not even good.<p>I used to be in the former camp and have moves to the latter. Consider cars. There are lots of &quot;car people&quot; who love to tinker with them, but most people just want to get where they are going.<p>It would be unreasonable to expect everyone to be a car expert, and it would also mean everyone would have to spend the time required to learn it. That would cut into time spent doing other things, which would be narrowing and wasteful. Instead of composing music or starting businesses or writing novels, people would be futzing with cars.
