A thought experiment: It's April, 1991. Magically, some interface to Claude materialises in London. Do you think most people would think it was a sentient life form? How much do you think the interface matters - what if it looks like an android, or like a horse, or like a large bug, or a keyboard on wheels?
I don't come down particularly hard on either side of the model sapience discussion, but I don't think dismissing either direction out of hand is the right call.
If it was in an android or humanoid type body, even with limited bodily control, most people would think they are talking to Commander Data from Star Trek. I think Claude is sufficiently advanced that almost everyone in that era would've considered it AGI.
People got attached to ELIZA. Why would I care what the general public thinks?
Interesting thought experiment.
I would say, if you put Claude in an android body with voice recognition and TTS, people in 1991 would think they are interacting with a sentinent machine from outer space.
