Ignoring the galactic algorithm bit, as it's in the quote but I think you get why it would cause a divide here, just because you could try to do something in a field does not mean that's what is actually being done in a field. This is what I mean by probing the edges of mathematics vs practical construction, using the same toolset to probe isn't enough to unite those two approaches alone.

Look at this paper as an example. Does its worst case Big O analysis attempt to model memory hierarchies for constructable systems or does it further diverge from any hardware considerations in favor of asymptotic behaviors towards infinities for a generic construction?
