I am not sure if anyone said that we will disapprove past science. The point here, like with everything we aspire for as programmers and scientists, is to improve what we have. Who knows what the future holds, I don’t.

Incidentally, many theories have been disproved and proved in Physics. And scientists will never rest; they will continue to re-invent, to invent, and to improve on what we have today. That is the simple point, to improve and see where it takes us.
