It is possible to construct a theoretical model of libertarian anarchism which will be compatible with modern scientific technology, but unfortunately it will not be socialist. It will be much closer to the views of Mr Goldwater and his economic adviser Professor Milton Friedman of Chicago than to the views of Kropotkin. For (as Bernard Shaw pointed out long ago in his pamphlet on the Impossibilities of Anarchism), the extreme versions of individualist liberalism are logically as anarchist as Bakunin.Not to mention Karl Hess or David Friedman. What's really funny about Hobsbawm seeing anarcho-libertarianism as suitable for the modern world is that he's known (some would say notorious) for usually taking a Whig-history approach to left movements, seeing them as more advanced the closer they are to Marxism and then Communism; in fact, it is for just that reason that he dismisses the classical anarchist movement, and Civil War-era Spanish anarchism in particular (see here and here for anarchist responses to Hobsbawm on Spanish anarchism), as quixotic and doomed to failure.
