1. Intelligence is information processing.
2. We will continue to improve our intelligent machines.
3. We are not near the peak of intelligence.
The author's first counterpoint is:
> Intelligence is not a single dimension, so “smarter than humans” is a meaningless concept.
Intelligence is information processing so "smarter than humans" just means better information processing: higher rate, volume, and quality of input and output. Aren't some humans smarter than others? And isn't that a power that can be abused or used for good? We don't have to worry about it being like us and smarter; it just has to be smart enough to outsmart any human.
He then talks about generality like it's a structural component that no one has been able to locate. It's a property and just means transferrable learning across domains. We're so young in our understanding of our own intelligence architecture, it's ridiculous to build a claim around there being no chance of implementing generality.
This statement is also incredibly weak:
> There is no other physical dimension in the universe that is infinite, as far as science knows so far...There is finite space and time.
There is evidence that matter might be able to be created out of nothing which would mean space can go on forever. We might only be able to interact with finite space, but that isn't to say all of nature is constrained to finite dimensions.
Even still, he doesn't make sense of why we need infinite domains. You only need to reach a point where a programmer AI is marginally better at programming AIs than any human or team of humans. Then we would no longer be in the pilot's seat.
