This is what I like to refer to as the "bias of computing." The idea is that we deal with so much scientific progress in our fields that we tend to think that scientific progress can take us anywhere and no restriction will stand up for long.

However, this is a fallacy that really has no grounding in the laws of physics. What reason do we have for thinking that information can travel faster than the speed of light? Moreover, what evidence do we have that the second law of thermodynamics could be reversed on a macro scale?

The assumption that all barriers will fall as others have seems unreasonable and contradictory to our current evidence.

Funny you should try to imply that our fundamental physics are somehow wrong in a serious way that we have a high chance of finding a deeper physics that shows "impossible" things by today's physics are possible (want to take bets on timeframes?), on an article about two space probes that have lasted 34 years out there because of our understanding of the fundamental laws. As for not understanding the "why" of inertia and gravity, we nevertheless have general relativity which is pretty darn good.
