You're not wrong. Here's a discussion and demonstration of 3D printed home drug synthesis labs you might find as interesting as I did. What isn't provided with such a lab is the education about diagnosing and prescribing, dosing, drug interactions, and all the huge volumes of information that come with professional careers in medicine, pharmacy, nursing, and more. It's because of the complexity of the human library of knowledge and the incapacity of any one of us to specialize in everything that I pin so much hope on AI. Not the big, world ruling AI of scifi, but the little AI that is this app or that app, to remind you of when to send birthday cards or change your oil, or how much Ivermectin to take to cure pinworms, vs. how much to take to cure lymphoma.
The chemistry reactor isn't really inexpensive, at least not this first prototype. It's not all that expensive though, either. I am unable to get treatment for an ailment I suffer that costs ~$250k, which is ~$25K per injection and some other equipment. The linked chemistry kit is a LOT cheaper than that!
Thanks!
