That's a weak ad hominem deflection. Readers be the judge.

Yes, the argument is MLKEM is so dangerous that it shouldn't be used alone. Even its codesigner says so. Why is it so hard to accept?

Take a look at the crypto from the 80's and 90's. They are considered bad jokes nowadays, badly designed and easily breakable. Why would the first-generation PQC algorithms be any different? Of course they're going to be broken and ridiculed in 20 years, in ways you cannot comprehend yet

The argument from Roberto Avanzi is reasonable: "as a codesigner of ML-KEM myself I would not trust using it exclusively: what if it gets broken mathematically and in the classical computational model (I.e. non-quantum)? Hybrid is better, and the additional time used by ECC is not significant."
