Assuming grid computing ends up cheaper, any problem that doesn&#x27;t depend on high availability.<p>Why grid computing might be cheaper: people could rent out excess capability that would otherwise go wasted, so their marginal cost of computing is 0 or close to 0. The question is how much overhead would be, but building on a marginal cost of 0 is better for costs than any dedicated solution.<p>It&#x27;s not obvious that those considerations outweigh the cost efficiencies of centralization, but it&#x27;s by no means obvious that they wouldn&#x27;t or can&#x27;t.<p>Think the power grid as an example. If power wasn&#x27;t fungible in close to real time (like cloud computing today, unless you specifically set it up that way) our prices would be more expensive, because less participants would be producing energy. The fact that anyone can, in theory, produce energy and sell it on a market which accepts the best bid improves the market for everyone. This seems similar.
