> I don't believe in 1+1=2 because it's useful for economics, physics, math, or whatever---I think it's true independently of its utility.
I actually doubt that. What do you think 11+27 is? If your answer was "38" then the followup question is: suppose it is 11:00. What time will it be 27 hours from now?
The "correct" answer to "what is 11+27" depends on circumstances in the real world (and so does 1+1). There are no Platonic truths, only preferred models.
> X is key for survival, so X must be true
It's not that. It's "X is a faithful reflection of the actual state of affairs in objective reality." That's what the word "true" means.
It just so happens that the actual state of affairs in objective reality has an impact on survival, so having a faithful reflection of it in your brain is handy. That's the reason "truth" is a thing.
> I'd prefer to not publicize my real name and face
Well, a podcast is voice only, so that's not really a show-stopper.
