Going through my checklist of what quantum computing companies have promised so far:
✔️ cure disease
✔️ solve climate change
✔️ solve food insecurity
Also, you often hear that quantum will improve AI, which in turn is supposed to speed up solving everything that AI has been promised to solve.

Some of you point out that the big players have used various tricks to keep their own $ safe. True.
That's why we need to think about how to prosecute them for fraud.
Those bubble-inflating claims - AI will cure all disease! end climate change! double lifespans! - are essentially Theranos X 1000.

They stole from all of us and fully plan to burn the planet.
They owe us - not the other way around. 1/3

A recent @nature.com article claims that classical (unquantised) gravity produces entanglement. We show that their model does not produce entanglement. Even if the model produced entanglement, it would be mediated by the quantised matter interaction, and not gravity. scirate.com/arxiv/2511.0... 🧪⚛️

Kudos for using the term "physics experiment" instead of "computer", and for coining "quantum FOMO".

Did you know that in 2015 quantum computers were supposed to go "faster than the universe"?
The power claim seems WAY inflated to me. A state vector sim of a 98-qubit 26-layer circuit costs ~10^-10 J * 2^98 * 26 * 98 ~= 10^23 J. Helios takes ~200ms*26 ~= 5 seconds for a sample, implying ~10^22 W not 10^49 W.
Regardless, it's no match for dwave's old "faster than the universe" plot:
