Where do people get this idea that future science disproves past science? It really doesn't work that way. We're not going to suddenly discover all of modern physics is wrong and oh hey look, it's easy to travel faster than light; that just isn't going to happen.
Newton discovered that F = ma, and that acceleration was the amount of speed gained per second. When he said this people were all like "man, if we could only find a vacuum we could take a small amount of mass and a large amount of force and move something faster than the speed of light!" (Which they semi knew due to some sort of cosmological event.) But Einstein came by and said "hold up, Newton is right for slow moving things, but as you approach C most of the force goes into increasing the mass of the object."
Imagine it goes the other way, in a few years some guy says "Einstein was right, but he didn't take into account the fact that we can effect the Plank constant within a certain radius of an horizon-tangle-event, so we can actually build something that will change the relative size of space around us and effectively move faster than the speed of light."
Which does not actually break Einsteins limit, although it does work like a Star Trek warp-drive. Of course the energy requirements are virtually impossible to satisfy in addition to all of the other problems.
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.
To be fair, OP was talking about the future.
