A lot of people seem weirdly aggrieved by the limit of the speed of light. It's not really the reason we can't go to space -- if you had magic energy density you could go to the stars in as little time as you wish, due to relativity. (Weird stuff happens when you try to come back, but nobody ever seems to care about that anyway.) I think people hear "Einstein said you can't go faster than the speed of light" and think, "Surely I can figure out how to be smarter than Einstein". It appears to be parallel to the ones who get cranky when being told that Newton says you can't make a perpetual motion machine. I suspect that they don't spend as much time thinking about the brain-in-a-box version is that it opens up too many scenarios that are hard to think about. If you decouple consciousness from bodies, who are you? Why not make multiple copies? Why go anywhere at all, when you could just stick the sensors there? People really want the cowboys in space, and get aggrieved that somebody told them they can't. So they focus on overcoming a limit that seems like it can be solved just by thinking really hard, and leave the engineering details to the peons with calculators.
