How can you be so sure that our mistakes don't manifest themselves? We might have failed to spot it, or we might have misinterpreted their manifestations. Or maybe we don't know where to look yet. Or maybe they don't manifest themselves.

The old joke "I can't think of anything I've ever forgotten" sort of applies here in an offhand way. How can we claim to know anything about what we don't know yet?

All we really know about faster than light travel is that we don't know how it could possibly be done. We have no reason to expect it to happen but we don't really know enough to say that it won't.
