Here, too, the authors argue that the ability to have non-problematic fluent conversations with humans is an ability that AI needs to be considered general AI.
“We will assume further that the ability to use language is not only a very good proxy for general human intelligence but also that it should be seen as a necessary condition for the existence of general artificial intelligence.”
And because the formalization and mathematization is not possible, there will be no AGI (artificial general intelligence). However, the authors wrote this pre GPT-2 and pre GPT-3, Lamda, and other, similar effective Chatbots.
I wonder if Barry Smith will have different arguments in his forthcoming book.
