This mechanosynthesis strategy is not limited to placement of isolated C2 units on the Si(100) surface. Once transferred, surface-bound IR-C2 structures can undergo successive reactions

Oh shit this is actually huge. Like, actually building real things huge.

Oh wow. I just re-read Drexler’s Radical Abundance recently after coming across an ancient job application I sent in to his lab like 25 years ago (I didn’t get it). I sort of assumed by this point I wouldn’t see real progress in my lifetime.

If and when this becomes mainstream, we're going to need better software than OpenSCAD, FreeCAD and Blender to actually design the things you want to build.

Can't wait for Big Matter. I'll be able to rent all of my surroundings which will all be slightly incorrect looking, and if I want it all to turn to goo and slither away I can just stop paying! I bet it won't even cause cancer.
