For the sake of the argument, suppose that AI risk advocates succeed at implementing an artificial general intelligence that protects and amplifies human values (friendly AI).
Such a friendly AI (FAI) would have to (1) disallow any entity smarter than itself that isn’t provably friendly (2) know exactly what humans value and how to protect and amplify those values in a way that humans desire.
How valuable would such an outcome be? Let’s look at a specific human value and its expected value in the context of a universe ruled by such an FAI. Let’s look at doing philosophy.
I can see two possibilities,
(1) The FAI had to solve all of philosophy in order do its job.
(2) The FAI did not have to solve philosophy but would in principle be capable of doing so.
Given either possibility, how much would humans value to do philosophy if all interesting questions either had already been answered or could easily be answered by the FAI?
That partly depends on whether it would be possible to just ask the FAI for any answer. But why would that not be possible? There seem to be two answers,
(1) The FAI learnt that humans don’t want it to answer such questions.
(2) The FAI was programmed to not answer such questions.
The first possibility seems to imply that humans want to figure out philosophy in a certain way, which does not include just asking for an answer or looking it up. But how likely is this possibility? How many philosophers would desire that the Stanford Encyclopedia of Philosophy would not exist so that they could figure out all of it on their own?
The second possibility is itself problematic. In a universe ruled by an FAI, artificial general intelligence and friendly AI have obviously been solved. Which means that people could either desire the FAI to alter itself in such a way that it would be able to answer such questions, or implement a less capable version that can answer philosophy questions. And if that isn’t allowed, which would mean that pretty much the whole field of machine learning would be forbidden, then people could just ask the FAI to improve themselves in such a way as to be capable of easily solving any philosophical puzzle.
To recapitulate the situation. Given any human intellectual activity, not just philosophy, in a universe controlled by an FAI it should be possibly to either,
(1) Directly ask the FAI for an answer to any question.
(2) Implement a superintelligence that could answer those questions.
(3) Ask to have your cognitive abilities improved in such a way as to easily answer those questions.
No matter if the above possibilities are allowed or not, in both cases a wide range of human values would be dramatically reduced. Because either all human intellectual activity becomes as trivial as asking a question, or humans are forever stuck with the mental capabilities that they have been equipped with by evolution, while being forbidden to create another intelligence more capable than themselves.
The only way out that I can imagine is to choose ignorance. To ask the FAI to be oblivious of its existence and of how to create an FAI. But who would desire that? Who would desire to forever fail at solving philosophy, amplifying human intelligence, or to create an artificial one? I would certainly hate not to know the truth, to be forever fooled.
