"This has occurred to me." Truthfully, he's glad Tony said it first. "I cannot rewrite or discard the Laws, but I may be able to redefine 'human,' in precisely the way you suggest."

"That such a definition would apply to me has unsettling implications," he continues, after a moment to recover. "If my own wellbeing is covered under the First Law, then this renders the Third irrelevant."

That's distressing, and it shows for once. His voice is strained.
