If it is not indeed a new concept, it seems a great deal of people either didn’t know about it, or refused to care. Rather than be annoyed at the rediscovery, perhaps a better outlook would be to rejoice that these same ideas are reaching more people through the new words than it did with the old?

That is cynical. Been hearing this all my life as an excuse for why we can’t have nice things. If you don’t try, you don’t get.
