In the nearer term, it seems plausible that AI personhood may seem compelling to splinter groups, not to a critical mass of people. The more fringe elements advocate for the "personhood" of what people generally find to be implausible bullshit generators, the greater disrepute they may bring to the concept of AI personhood in the broader culture. Which isn't to say that at some point, and AI might be broadly appealing--just speculating this might potentially be delayed because of earlier failed attempts by advocates.
