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 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.
