This is an impressive amount of hubris. Does the author assume that all the certifications and testing stages were for show? I don't hold the highest view of LessWrong and the whole rationalist shtick. This post exemplifies why. Underneath this post is the assumption that the author is so much smarter than everybody else because they are Rational with a capital R and can therefore harness the power of science to make…
Um... are you reading the same post as the rest of us? He's just trying out something an actual expert has made to see if it works when he tries to do it. So far it hasn't worked, as he admits, but it certainly could. Sure, it's probably with greater cost, higher risk and less effectiveness than the mass produced vaccines I expect (and the author would likely agree). But it's certainly not the case thay a layman can…
Theoretically this might be true, but in practice it seems obvious that this will fail. I can think of so many ways in which this could be subtly invalid and I am in no way an expert. I would expect someone with commercial lab experience or vaccine production experience to be able to point out a hundred ways in which this won't work.
Maybe the more obvious problem though is that we can't know if it works either. Without a valid scientific study on the effectiveness it's all just a guess. To call it a vaccine is hubris because it is precisely this study that deems a concoction of ingredients to actually be a vaccine. I'd expect Less Wrong to be the first place to point out all the flaws in the idea of just getting an antibody test to decide if it's working.
