It's unclear whether this is true or not. Prior to literacy bring widespread, it may have been looked at similarly: "I'm good at tailoring, you can't expect me to learn to read and write like a monk". But as it turns out, most people are actually capable of literacy. It's doesn't mean they become hemingways, but it allows them to do all sorts of jobs they wouldn't otherwise be able to do if we believed that literacy was a matter of personal taste or what you're "good at".

Perhaps the same is true of CS: we don't need everyone to be Hemingway here: plenty of jobs just need programming. I'm not sure what the alternative would be. Even if CS turns out to be above the capabilities of most people, that certainly shouldn't mean that it's a reasonable choice to spend an equivalent amount of money getting a degree that well known ahead of time to not get you a return.
