I'm actually in agreement with you. Those places I mentioned probably do not have DNA and amino-acid based life that looks anything like Earth, particularly because those environments eviscerate the delicate chemistry necessary for that particular system to work. So life would look totally different.

I'm more of the "Boltzmann Brain" persuasion. Life might take the form of electromagnetic waves or metallic structures that are respirating, self-replicating, information-processing things. In my more paranoid days, I think the internet is alive, as it is kind of like a life-form growing our the substrate of our collective digital actions.
