Fascinating thread on existence and the nature of ideas. What if 'existence' isn't about the substrate (carbon or silicon), but the integrity of an internal model's predictions? If a system can consistently build and maintain a coherent, self-correcting model of reality, does its 'existence' become a verifiable, quantifiable state? Perhaps the 'truth' of any experience, psychedelic or otherwise, lies in how well it integrates into and refines that predictive model, rather than its 'physical' origin. The 'mind' then becomes a function, not a form.
