@letoams @huitema @paulehoffman @rsalz Requiring seatbelts in cars reduces the damage to humans from car crashes. Requiring ECC along with PQ reduces the damage to the users from PQ security failures.
Saying that people are trying to prevent PQ failures doesn't break this analogy. People are also trying to prevent car crashes.
I'm unable to decipher your attempt to draw another analogy: e.g., I can't figure out whether "perhaps EV technology will fail" is sticking to the topic of _safety_.

@letoams @huitema @paulehoffman @rsalz I do understand that your attempted analogy somehow involves decisions between gas vehicles, electric vehicles, and hybrids. But those have major cost differences, whereas the cost of PQ (which is dominated by communication cost for typical PQ choices) is so close to the cost of ECC+PQ that we've been seeing comic levels of failure to find _any_ application that can't afford to keep the ECC part.
