I wouldn’t have a complaint about that. There’s so much out there in space to explore and it would be fun to see some of it at least.
Time will tell.
My guess is (this has been in there a while, and I've droned on about it before) is that there are a number of planets beyond Pluto, but they move in retrograde, not unlike most of the outer minor moons of Jupiter. A probe could be the key to finding out one way or another.
