You said it could be developed for just 100 million dollars and I said I
very much doubted that price estimate. The James Webb Telescope was
originally suposed to be launched in 2007 and cost 825 million dollars, but
as of this date it has cost 10 billion and it's still sitting on the ground
doing nothing. Space telescopes are very expensive and take longer to make
than you'd expect even if you take Hofstadter's Law into account.
Hofstadter's Law says It always takes longer than you'd expect even when
you take into account Hofstadter's Law.

I don't think anybody on the planet could give a price estimate on that
that was worth a damn.
