This is the part I think people on both sides of this debate are missing.

A QC powerful enough to crack 256-EDCSA will probably take something the size of the moon. Due to the amount of error correction and cooling infrastructure to keep that many qubits at absolute zero (which is required for them to remain entangled).

So, yea, the quantum apocalypse is probably not near.

HOWEVER. This viewpoint ignores the possibility of future breakthroughs. It only took a few breakthroughs to go from computers the size of a garage to computers the size of a wallet. And IF a few small breakthroughs happen in Quantum, the path toward a Billion qubit (logical) QC may be trivial.
