PSD2 only took effect in 2019, and for many countries the enforcement was delayed for card payments up to a full year due to lack of issuer readiness.
2FA is absolutely the future and I believe globally payments should move in this direction… I’m just pointing out that even in Europe, this has not been the standard for all that long. That said I hope other countries/regions follow the example — the EEA seems to lead the charge on major online issues, e.g. payments and privacy.
I think what I get hung up on with explanations like this is, what changes once the wave function has collapsed? Are there observable characteristics before wave function collapse that become different after the wave function collapses?
Maybe this question just reduces to “how can we tell the difference between two entangled particles having always been in some state (but we didn’t know it) vs. being simultaneously in both states until we make a measurement?”
Based on other comments in this post, it seems like the answer may be: Bell’s theorem proves that classical explanations have an upper bound on correlations between the particles, but quantum mechanics predicts a correlation the violates the classical upper bound. And we can experimentally test the correlations in practice.
