I would definitely need to try some bits a few times. Less with the biology and more organic chemistry, which is the stuff that sometimes fucks up even when you do everything right.

And there are little gaps. Like i could walk you through decent-ish steel but I don’t know fuck-all about copper alloys, and might have to fuck around woth implementation a whole bunch on a few steps. It wouldn’t be personally fast, but it would be civilizationally fast.
