I see no reason that human level intelligence (and beyond) need be constrained to a biological substrate. I do not know who said this originally (it’s not original with me), but we often overestimate what is achievable in the short term and underestimate what is achievable in the long term.
Some day folks (or AI’s!) will think of ChatGPT and its ilk in the same way as kids today think of landline telephones or LP records.
