It’s not an objection. Somebody said “[x thing] is impermanent” and the rebuttal you posted was “human life is also impermanent”

That’s not really a rebuttal to the notion that everything is impermanent, that supports it.

Anyway a wizened crone told me I’ll die on 11 September 2098, so let’s give me two weeks to gloat. Two weeks before that date. I will bet you that it happens on or before that date. Props for taking the over that no collisions of SHA-2 will happen before then
