It's not about having to learn things; it's about the required methods of using the tool going directly against the grain of the way people in general operate.

The classic "you're holding it wrong" was about the iPhone 4: sure, people could learn to hold the iPhone in such a way that they didn't block the particular parts of the antenna that were (supposedly) the problem. But "holding an iPhone" is a fairly natural thing to do, and if the way that people are going to do it naturally doesn't allow its antenna to connect properly, then that's a technology problem, not a human problem.

If the selling point for AI is "you can just talk to it, and it will do stuff for you!" (which may or may not be yours, personally, but it is for a lot of people), then you have to be able to acknowledge that "describing a problem or desire using natural language" is something that humans already do naturally. Thus, if they have to learn to describe their problem in very specific ways in order to get the AI to do what they want, and most people are not doing that, then that's a failure of the technology.

For the specific case at hand, what's being described is similar to the problem of self-driving cars: you're selling the benefit as being the AI taking a lot of the work off your shoulders; all you have to do is constantly check its work just in case it makes a mistake. Which is something that we already know, empirically and with lots and lots of data, that humans are bad at.

Once again, it's a technology issue. Not a human issue.
