Earlier quoted context omitted.
AGI should obviously be able to do them. But AI being able to do those 100 percent wouldn't be evidence of AGI however. It is a very narrow domain.
Why not? If the only thing that can solve problem X is AGI (e.g. humans), and something else comes along that solves it, then rationally that should be evidence that the something else is AGI right? Unless you have strong prior beliefs (like "computers can't be AGI") or something else that's problem specific ("these problems can be solved by these techniques which don't count as AGI"). So I guess that's my real quest…
AGI can add 1+1 correctly, but an ability to do that is not a test for AGI.
