For decades, the concept of “personhood” as a moral category based in a very Cartesian conception of consciousness/cognition has been wreaking havoc on philosophy. Example #1000000000 is the AI stuff.
For people who deny AI personhood for any AI model at any point in the future, you're going to need better arguments than this. There are arguments out there, but once agents can solve Navier-Stokes, write music and poetry, and provide people with seemingly fulfilling life advice, this kind of line is just not going to be persuasive. "YOU'RE CRAZY" no longer lands.
