As far as we know, there's no way to get around the lightspeed limit, which implies no matter how advanced a civilization gets, they would be constrained by physics and available resources - so no warp drives, no stargates, nothing but rockets and things that work like rockets, and generations of travel between the stars.

If that's the case, it any form of space travel, much less long term interstellar travel, might be an exception rather than the rule for intelligent species. We only assume that expansion out into the stars is a natural consequence of progress due to biases we have regarding biological and societal evolution, but space isn't just a bigger ocean.

We can't really extrapolate the likelihood of visitation by extraterrestrials from the historical tendency of cultures to encounter one another on our own planet. Given the vast size of the observable universe and the unremarkable nature of the Earth (from which we've only been broadcasting signals for a fraction of an instant, relatively speaking) it's not at all surprising that we wouldn't see anyone or that no one would see us, much less stop by for a visit.
