I won't dream of a single (or multiple) damn quantum thing until I see an equation that describes a real-world superposition scaling limit, species type "immovable object".
I believed in Moore's law because it was on a collision course with the atom, right from day one. Even as a child, I didn't believe in a Laplacian universe, in the sense that the accumulated knowledge required to compute the deterministic outcome could exist in one place—a place smaller than the universe itself—for any value of "smaller" my small mind was capable of entertaining.
I've been reading articles about quantum computing seemingly for decades now, and not a single article has pointed out any practical scaling limit. For all these dunderheads seem to know, we could cajole the entire universe into a state of Laplacian superposition, if only we didn't suck at stacking these tiny little Lego blocks.
No scaling boundary equation widely promulgated = no credibility widely disseminated = very little fantasy action for people who don't believe in giant green men with anger management issues.
