I agree with you for the most part kind sir. Technology is there but it's just stressing theory for now. And nothing can be concluded on that note.
While I have done mdma (at least real one time or so) while heavily depressed and I believe it to give a fake demeanor of happiness.
Whereas psilocybin can procreate that happiness. It also derives a split in the cycle that is depression and I think can aid to alexithymia. Aka..forcing some reaction via neurons being acted. Source for this is the college at London sorry for non specifics.
And for the culture of psilocybin and what it can do you may refer to Terrence McKenna. Please to whom anyone who probably thinks I'm just that dope head don't I am in college and studying often electrical engi.
