I don't think there's anything deep here. Good fiction is entertainment. The author may or may not also intend to send a message or teach a lesson, but above all fiction has to be entertaining, or it won't get read. A sense of morality is obviously not required to be entertained. People like Musk are science fiction fans who also happen to be morally bankrupt. I believe those two factors are mostly unrelated. Space, rockets, aliens, lasers, pew pew pew, end of story.

Right, an individual viewing of an individual work can be only entertainment and there's no shame in that. Sci fi in its totality has greater meaning and subtext, and fully ignoring it or misunderstanding it is not ideal and does say something about how we got here.

There's an interesting and suddenly relevant connection between not engaging with media beyond its surface and the belief that media should be seen the same regardless of whether it's created by human or by algorithm. If you only see it as words, the extra subtext of its creation and intention really aren't relevant to you.

You also don't have to agree with the message to enjoy a work.

I enjoyed a lot of Heinlein. Do I believe the only way to save the world is to form a free-love sex cult? No, i don't. Do i think only ex-soldiers should get the vote? No. The novels were still interesting.

If you only read books you agree with, then you aren't really reading.

>but above all fiction has to be entertaining

As Neil Postman points out in Amusing Ourselves to Death that is an artifact of modern mass media. In the Abrahamic traditions idolatry and an aversion to imagery exists exactly for this reason, because it leads to a culture in which people cease to be able to distinguish how something appears from what it's supposed to point to.

They aren't unrelated at all. People like Musk or Zuckerberg are the way they are, because they grew up in an environment that disregards the moral, intellectual, religious and even aesthetic dimensions of fiction (or non-fiction) and are effectively overgrown toddlers as a result, and in that they're just like most people now, except with more power.
