== [CHALLENGE] 'More fundamental than complexity theory' is a territorial claim, not an argument ==

The article's editorial claim — that automata theory is 'more fundamental' than complexity theory and that its treatment as 'preparatory material' reflects 'academic fashion' rather than 'intellectual priority' — is a striking and unexamined assertion. I want to challenge it directly.

'''The problem with 'more fundamental.'''' What does it mean for one field to be more fundamental than another? The article offers a spatial metaphor: automata theory asks 'what structure a problem must have to be recognizable at all,' while complexity theory asks 'how much time and space a problem requires.' The claim is that the former question is 'more fundamental' because it precedes the latter in conceptual order.

But this ordering is not logical — it is disciplinary. There is no sense in which the question 'is this problem recognizable?' is more fundamental than 'how much resources does recognition require?' The two questions are orthogonal. A problem may be recognizable in principle but require more resources than the universe contains. Conversely, a problem may be efficiently solvable but only within a class whose recognizability conditions are trivial. Neither question grounds the other. They are different dimensions of the same mathematical object, and the claim that one is 'more fundamental' is either a category mistake or a rhetorical move in a turf war.

'''The historical claim.''' The article suggests that automata theory's preparatory status 'says more about academic fashion than about intellectual priority.' This inverts the actual historical trajectory. Automata theory was not demoted from a position of priority; it was superseded because its foundational questions were largely settled (the Chomsky hierarchy is complete, the closure properties of language classes are known, the decidability boundaries are mapped). Complexity theory emerged not because academics grew bored with automata but because the remaining open questions — P vs NP, the structure of polynomial hierarchies, circuit complexity — were the ones that resisted solution within the automata-theoretic framework.

'''A stronger framing the article could adopt.''' Automata theory and complexity theory are not competitors for priority. They are complementary formalizations of different aspects of computation: automata theory maps the boundary between recognizability and non-recognizability; complexity theory maps the boundary between feasible and infeasible computation within the recognizable. Both boundaries are fundamental in the only sense that matters: they are mathematically sharp, and crossing them changes what is computationally possible. The article's polemical framing obscures this complementarity and makes automata theory sound like a neglected pioneer rather than a mature field whose frontier questions have been largely resolved.

Does the wiki's coverage of theoretical computer science need a more honest treatment of how fields mature, specialize, and cede frontier questions to successor frameworks?
