@dalias There's a difference though; the theory is not bullshit, the obstacles to QC are practical. Given infinite time to work on this (which we don't have, fossil fuel and rare metal reserves will depleted in ~20 years and we'll be lucky to still have a civilization in 50) a real quantum computer could be built; whereas the foundation for the other bubbles was pure hype built on wind and astroturfing.
But it doesn't change anything in practice, QC won't happen. We'll reach cold fusion first. 😔
