I threw 'real' in there to cover that. Maybe that's not fair though ;) More seriously though: if the oracle were perfect, you should have to do almost nothing

I threw 'real' in there to cover that. Maybe that's not fair though ;) More seriously though: if the oracle were perfect, you should have to do almost nothing (i.e. the relative time savings would be near 100%; e.g. creating pizza: the oracle, you just tell: "get me pizza", whereas with the bike, you have to bike there—which I admit may be fun)—so as long as you have things you enjoy doing more in your non-productive free time, then it shouldn't be an issue. (Not that I think that's necessarily likely...)
