> I know of no biological forms that have evolved wheels. But wheels have turned out to be a hell of a lot faster than fins or legs. On certain terrain. And much slower - sometimes useless - on others. Wheels aren't simply better legs, they're a different way of moving, with its own benefits and drawbacks. Likewise, if we're talking about computational ability, we already have things that are faster than the human brain in certain areas (say, numerical computation). When we talk about AGI, we're talking about human-like intelligence (at least to a certain degree). So we already have the wheel, but now we want to develop something that does what the leg does. Now, maybe that doesn't have to be an actual leg, but that's usually what people usually end up with when they try to find something that will have a similar functionality as a leg.
