First off, async/await is promises. It's merely syntactic sugar. The point of async/await is not to never have the word "Promise" appear in your code. It's also not meant to be universally better than using Promises bare-bones.
A lot of the argument appears to be the author extrapolating from his own lack of familiarity to others: "We are taught", "our minds", etc. I can easily construe some hypothetical person with a certain set of skills (and lack thereof) that would have just as much trouble with bare-bones Promises. But I don't have to because the author did it for me at "One more thing…".
"People can mess this up" was never an argument. You can mess everything up. The more interesting question is how badly and how often.
