While I agree that artificial intelligence can theoretically in time become advanced enough to be sentient, it doesn't seem to be anywhere close to that currently.

Computers aren't biological creatures. They don't have any self-regulation or internal motivations guiding their actions/beliefs. It's not possible for the AI to be "brainwashed", because that would imply that it had a pre-existing personality and set of goals.

It's also not entirely fair to say that humans only take in ideas and remix them. If that was the case, then there wouldn't be any art or writing to begin with. Our creative output is prompted and directed not only by the world around us but the world inside us as well.

When we try to express a concept like "love" through writing/drawing/song, we're not only outputting a reflection of our society/culture's perception of "love", we're also filtering it through our own personal interpretation of what it means to us as biological creatures. It's a strong internal desire that pushes us to form communities and raise our young, and that's shown not only in the art we produce but also in the fact that we're even making the art in the first place.

Sure, you can give a prompt to ChatGPT or other AI applications and have it output something similar to the kind of emotionally-driven creative works that humans create, but even having to give a prompt in itself is a significant difference between AI and actual sentience. Humans don't need prompts, we create out of our own volition due to our own internal motivations/desires. A human taught from birth that they were a computer would likely be able to break free from that "programming" pretty easily even without intervention. All you'd have to do is stop feeding them.

Unless some AI app starts talking to us unprompted, I don't think the idea of it possibly being sentient is even an issue. If the AI doesn't have any actual internal motivations or desires, then whatever perceived signs of sentience it might display are likely just pareidolia.
