In 1998 he would have probably said that DOIs are unnecessary. They may indeed be, from a technological standpoint, but from a social and business (sustainability) standpoint they've clearly been hugely successful. So I think the question that matters much more is, is there (or will there be) a similar ecosystem and environment for LSIDs that will make them equally useful.
