When theory of computation questions are analyzed on physical machines having physical memory running out is stack space is possible, thus changing to subject to something else as a type of rebuttal is still the strawman deception. -- Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
