This is basically the Turing test, and like the Turing test it undervalues other elements which can allow for differentiation between “real” and “fake” things. For example - if we can determine that a thing that looks, walks, and quacks like a duck, but doesn’t have the biological heritage markers (that we can easily determine) then it won’t be treated as equivalent to a duck. The social desire to differentiate between real and fake exists and is easily implementable.

In other words: if AIs/robots ever become so advanced that they look, walk, and talk like people, I expect there to be a system which easily determines if the subject has a biological origin or not.

This is way down the line, but in a closer future this will probably just look like verifying someone’s real world identity as a part of the social media account creation process. The alternative is that billion dollar corporations like Meta or YouTube just let their platforms become overrun with AI slop. I don’t expect them to sit on their hands and do nothing.
