I don't think that is a very accurate analogy, and in any case, the 
argument is not that we should immediately cease at once all the 
things we do with DNS today.

DNS is one of the more centralised systems of the Internet at large; 
it works because of its reliance on intermediate caching and 
end-to-end accuracy.

It seems to me the claim is more that DNS was not designed to handle 
them and that if this is what we want to do, perhaps something should 
supplant DNS, or, alternate methods should be used.

For example, perhaps in the case of CDNs geographic optimisation 
should be in the province of routing (e.g. anycast) and not DNS?
