I guess the better question is "when?" >unless you believe that there is something about biology that makes it categorically better for certain kinds of computation.There's no reason to believe that's the case. How about the fact that we don't actually know enough about the human mind to arrive at this conclusion? (yet)
> Maybe? I guess the better question is "when?" And also at what cost and at what scale? Will we be able to construct a supercomputer/datacenter that can match or exceed human intelligence? Possibly, even probaby. But that would only be one instance of such an AGI then and it would be very expensive. IMHO it will take a long time to produce something like that as a commodity.
A tractor can't reproduce or repair itself, but it is better than a horse for farming. A self-driving car can't learn by itself, but a datacenter can use its data to train a new version of the car software. A humanoid robot by itself might not be flexible enough to count as AGI, but it can defer some problems to an exascale datacenter.
