These questions are ridiculous because they conflate "intelligence" and "sentience", also known as sensory experience or "qualia". While we often have a solid epistemic foundation for the claims we make about intelligence because we can measure it. Sentience is not something that can be measured on a relative spectrum. Spontaneous emotional and sensory experience are entirely independent of intelligence and most definitely independent of an external prompt.
You are right that infants are DEFINITELY sentient, but how does that have anything to do with Lemoin...
I submitted a proposal but did not receive a confirmation that it was received. Perhaps I should submit again?
