Interesting article. I am also skeptical that we are going to see useful quantum computers anytime soon. Since at least 2019, I have been saying that this is hard. And that we don’t know if it’s “land a person on the surface of the moon” hard, or “land a person on the surface of the sun” hard. They’re both hard, but very different.
