I've been thinking about this a bunch lately and very much agree. We really need a way to build these nanodevices that doesn't involve lithography. Using something like DNA to carry information to the surface seems way easier and more effective/robust as we continue to scale down and out.
- __MatrixMan__ 2y agoI wouldn't go so far as "way easier". It's just difficult for a single reason that's easy to imagine a solution to rather than 100 different reasons which are not. I'm not in the field, but I'm under the impression that our ability to encode our wishes into DNA is closer to: > make me a 1um tall pyramid out of nanoparticles which are all the same type ...than it is to: > make me a NAND gate out of this solution of nanoparticles, some are doped in different ways than others. Most miracles involving DNA are heavily inspired by nature, and there's not a lot of natural code available for the construction of logic gates. I'm not sure which of these is harder: 1. make biochemical systems which construct arbitrary solid state circuits 2. abandon solid state and do our computing in living tissue What I like about the former is that there are a lot of other things that investment in that area might produce, things which aren't a hassle to keep alive, even if a general purpose circuit constructor happens to be out of reach.
