[1] is an entertaining argument, but as you know, real brains involve more than a massive free scalar. :D
I do like that balding seems to take about a light-crossing time in the cosmic no-hair in [1]. You'll need some extra patience as you approach fluctuation-free de Sitter, but there's surely infinite patience somewhere in an infinite-dimensional Hilbert space. The trick is how to walk the path from here in that space to there in that space.
I'm not sure [2]'s cognitive instability matters. We do use effective field theory all the time. Heck, even in that paper. We can have useful predictions without having final/total/exact answers.
