I agree, photolithography at home is a long way out.

I think if we want to distribute the means of computational production, a better approach would be to print oligonucleotide instructions (requires a custom inkjet printer), and use a cell free extract (e. coli would work) to synthesize proteins which are programmed to assemble the computational substrate from nanoparticles.

Something along these lines: https://www.pnas.org/doi/10.1073/pnas.1422649112

That being the better approach says volumes about the complexity of lithography.

For anyone reading this, read Chip Wars by Chris Miller. The Lithography sub-story that threads through is amazing and fascinating and the whole book is incredible besides.

For those who think Ai Is a bubble and longshot, look up how crazy of a bet EUV (extreme ultraviolet) lithography was.
