@Mitch Yeah, our current medical tech is both miraculous and very very limited. There are "surgeons" who, eg, claim to be able to re-attach a severed head. That's just total bullshit, however, we do have a very good understanding of why it's bullshit, and know a lot of things that we need to learn/invent in order to turn it from sci-fi to science. I'm no biologist but I do think, barring major catastrophes, we will be able to assemble organisms from parts in the next 50-200y
