      If you think about it, a lot of crypto vulnerabilities come down to code that was meant to optimize/speed things. Heartbleed, most RSA problems, DH prime generations, ROCA, ...

      but speed drives adoption. Non-security people usually care more about speed/convenience rather than security.

      I disagree. Even unoptimized implementations are fast enough for most applications. Yes, even on a cheap mobile device.

          yeah definitely, I agree with your statement. People saying SHA-3 is too slow for their application (compared to K12) are (almost) always wrong. But even with this, uneducated decisions will choose what is faster if given the choice.

          RSA > 2048 without CRT on a smartcard highly disagrees with you. But that's why everyone is now using ECC. :3

          in the defense of Frank comment I'd say that smartcards are not included in the "most applications" (even though they are a widespread illustration of the problem)

          This ignores impact of standardization. Apple needed Curve25519 to encrypt push messages and meet battery lifetime+security goals

          Benefited from having same extensively optimized implementation. if they had to use ideosyncratic system, would suffer
