As compared to polygon based models, I think voxels are a more accurate way of modeling actual 3D objects.
Also seems closer to how 3D printing would work.
AI already creates software, hardware is next. Several companies like Circuitmind, Cells and JITX are starting to use AI to do hardware design.
Why we need Zero Knowledge Proofs ZK proofs are a better solution for ensuring trust for all kinds of contractual and financial interactions.
