The Human Automata by Benyakir Horowitz

Jules Winters is certain of his destiny, to be a great man and inventor on par with geniuses like Edison or Carnegie. He may not have accomplished anything yet, but a terminal disease seems to be just the salvation he needs. It’s a call to arms with one solution, remake himself as an immortal, future-proof robot. His humanity is worth nothing compared to what he could accomplish without it. As a tireless machine, he could uplift the impoverished and make them valuable members of society. He’s so certain that it’s the best solution that there’s nothing that can dissuade him, not the incredible pain that comes with each step of his transformation, not the disregard he feels from his wife’s family, and certainly not the creeping feeling that no one will ever care about his masterwork.
