Yes, we are in violent agreement then. Easy to generate random hard instances does not at all mean that highly structured "non-random" instances can't be hard.

Yes, we are in violent agreement then. Easy to generate random hard instances does not at all mean that highly structured "non-random" instances can't be hard. The "phase transition" only means that the fraction that are hard at a given non-critical ratio decreases with n, but there very well could be a large absolute number, that increases with n. The space of problems of size n grows exponentially, after all.
