Haven't had one of these for awhile. This thread is for questions or comments that you've felt silly about not knowing/understanding. Let's try to exchange info that seems obvious, knowing that due to the illusion of transparency it really isn't so obvious!
Read "rate of learning" as "time it takes to learn 1 bit of information"
So UFAI can learn 1 bit in time T, but a FAI takes T+X
Or, at least, that's how I read it, because the second paragraph makes it pretty clear that the author is discussing UFAI outpacing FAI. You could also just read it as a typo in the equation, but "accidentally miswrote the entire second paragraph" seems significantly less likely. Especially since "Won't FAI learn faster and outpace UFAI" seems like a pretty low probability question to begin with...
Erm... hi, welcome to the debug stack for how I reached that conclusion. Hope it helps ^.^
