I believe the point is that quantum computers allow you to manipulate a linear combination of bits, whereas simulating the weather would require non-linear combinations. It's unclear how a QC would help simulate something like that better than a classical computer.

Quantum algorithms are nonlinear. If someone is saying "quantum mechanics is a linear theory" as a counterargument to anything QC related. Then that person has no idea what they are talking about. Because they likely never cared to learn event the basics of QC.

I don't think it's quite as simple as that:

"New Quantum Algorithms Finally Crack Nonlinear Equations. Two teams found different ways for quantum computers to process nonlinear systems by first disguising them as linear ones."

Quantum mechanics is a linear theory. That's not an erroneous statement.

Quantum computing and quantum mechanics, not the same thing.
