I'm not saying this will happen, but it seems to me like an incredibly silly move.
We barely understand how consciousness works, we should stop talking about "AGI". It is just empty, ridiculous techno-babble. Sorry for the harsh language, there's no nice way to drive home this point.
Since Shank's comment didn't specify what they meant, I should have made a more charitable interpretation (i.e. assume it was "weak AGI").
I suspect AGI is quite possible, it just won't be what everyone thinks it will be.
Human behavior is highly optimized to having a meat based shell it has to keep alive. The vast majority of our behaviors have little to nothing to do with our intelligence. Any non-organic intelligence is going to be highly divergent in its trajectory.
