It's not really the technology, it's more the skill of the artisan. Forget
mass-produced mirrors. Cave mirrors were every bit as good as anything made
today. Unless you are talking about the glass material itself, which has
improved, with Zerodur etc., or that it's is a bit easier these days to
produce a fine mirror. Refractor lenses are another question.
