Re: [sl4] trade or merge?

If the intelligence of an selfimproving AI is on the rise, exponentially,
why would it ever wanna 'merge' with another AI?
Or are we imagining that there's an upper limit to the capacity of an AI
where it makes a case of diminishing returns to throw more hardware at it,
that the design simply cannot(even hand crafted by an uber AI) scale beyond
some level. In extension of that we imagine that it might make sense to
cluster these things to go beyond the single-ai instance performance.
Is that what we're talking about here? :-)
