It's quite possible that GI and thus AGI does not actually exist. Though now the paper the other day by all those heavy hitters in the industry makes more sense in this context.
Aren't we humans supposed to have GI? Maybe you're conflating AGI and ASI.
Supposed by humans, who might not be aware of their own limitations.
Show me where GI is and how to measure it in a way that isn't just "it's however humans think"
