>I guess I have not thought critically why we couldn't use a Transcendental argument to support Descartes.

The previous section within the Transcendental Dialectic that focuses on the nature of the soul goes into a refutation of Descartes' statement. Kant basically finds "I think therefore I am" to be a tautology that only works by equivocating the "I" in each clause. "I think" pretends that the "I" there is an object in the world which it then compares to the "I am" which is an object in the world. Kant argues that "I think" does not actually demonstrate an "I" that is an object but rather a redundant qualification of thinking.

I am being a bit imprecise, so here is SEP's summary:

>For in each case, Kant thinks that a feature of self-consciousness (the essentially subjectival, unitary and identical nature of the “I” of apperception) gets transmuted into a metaphysics of a self (as an object) that is ostensibly “known” through reason alone to be substantial, simple, identical, etc. This slide from the “I” of apperception to the constitution of an object (the soul) has received considerable attention in the secondary literature, and has fueled a great deal of attention to the Kantian theory of mind and mental activity.

>The claim that the ‘I’ of apperception yields no object of knowledge (for it is not itself an object, but only the “vehicle” for any representation of objectivity as such) is fundamental to Kant’s critique of rational psychology.

>other techniques include Kant's Transcendental Deduction or Descartes's pure doubt

This is not quite accurate. Kant says very explicitly in the (rarely studied) Transcendental Doctrine of Method (Ch 1 Section 4, A789/B817) that this kind of proof method (he calls it "apagogic") is unsuitable to transcendental proofs.

You might be thinking of the much more well studied Antinomies of Pure Reason, in which he uses this kind of proof negatively (which is to say, the circumscribe the limits of reason) as part of his proof against the way the metaphysical arguments from philosophers of his time (which he called "dogmatic" use of reason) about the nature of the cosmos were posed.

The method he used in his Deduction is a transcendental argument, which is typically expressed using two things, X and Y. X is problematic (can be true but not necessarily so), and Y is dependent on X. So then if Y is true, then X must necessarily be true as well.

People who don't do intense security work for a living underestimate the complexity of it. This might find some vulnerabilities, but it's not really capable of producing new methods and attacks. What it replaces isn't a high quality human researcher; it replaces current static code review systems.

If AI models never had stack smashing writeups in their corpus, they'd never be able to invent stack smashing.

>Auditors though, they are cooked.

I think you're massively underestimating the complexity and depth of a good security audit service.
