The idea that there are singular indivisible intelligences within the Central Nervous System is a false notion. The truth is that every intelligence is a collective of something, as seen in the biochemical and bioelectrical signals of the body.
The debate over whether AI can mimic human emotions continues as there is no agreement on whether AI can replicate human emotions, including love, hate, fear, and joy, which are valued more than information processing by humans. Ultimately, understanding consciousness will pave the way for answering this question.
The idea that if an AI is sufficiently close and similar to us that we merge with it, then to all intents and purposes, that AI is conscious like us is explored. Consciousness and specifically consciousness as one of the great inventions is discussed in this episode.
The components of intelligent beings manifest consciousness, making it plausible that we could create intelligent beings. It is unclear whether there are intelligent alien civilizations out there, but there are enough planets for the possibility, and some intelligent life on this planet is still not fully understood.
The brain has the potential to adapt to different inputs such as prosthetic devices and sensors which could potentially expand its capabilities beyond what we currently understand.
