Earlier quoted context omitted.
Saying we don't "need" AGI is like saying we don't need electricity. Sure life existed before we had that capability, but it would be very transformative. Of course we can make specialized tools in the mean time.
Can you give an example how it would be transformative compared to specialized AI?
Because we evolved to get where we are, humans have all sorts of messy behaviours that aren't really compatible with a utopian society. Theft, violence, crime, greed - it's all completely unnecessary and yet most of us can't bring ourselves to solve these problems. And plenty are happy to live apathetically while billionaires become trillionaires...for what exactly? There's a whole industry of hyper-luxury goods now, because they make so much money even regular luxury is too cheap.
If we can produce AGI that exceeds the capabilities of our species, then my hope is that rather than the typical outcome of "they kill us all", that they will simply keep us in line. They will babysit us. They will force us all to get along, to ensure that we treat each other fairly.
As a parent teaches children to share by forcing them to break the cookie in half, perhaps AI will do the same for us.
