I understand it's very different and that it isn't likely to replace non-quantum computing in our lifetimes, if ever. It doesn't need to replace general computing to threaten public key crypto. It jus...
Quantum computing's potential to break public key cryptography is a serious concern. The fact that non-QC attacks against P2PKH already exist and that SegWit adoption is crucial to mitigate some risks is important. Determining the extent of P2PKH vulnerability and tracking adoption rates is a worthwhile endeavor.
