Why is Bitcoin the focus of quantum computing? Isn't everything over at some level of compute power?

I genuinely do not understand the fixation of Bitcoin dying due to quantum computing.

Once we have legit quantum computers isn't nearly everything at risk?

Why don't I hear stories like "Banking needs to update within 2-5 years before quantum computing." Or, "Privacy will end in 5 years when quantum computing is available."

It feels like everything will be fine I'm the face of quantum computing except Bitcoin. What am I missing?

This is from Charles Edwards on X:

"A quantum computer will break Bitcoin in just 2-9 years if we don't upgrade. With high probability in the 4-5 years range. This is the timeframe all quantum experts converge on. Don't believe the naysayers. We have already entered the Quantum Event Horizon: the frontier risk of a quantum hack is the same amount of time away as upgrade consensus and roll-out. We must act in 2026. Let's finish and deploy BIP 360."
