Voyager 1 was launched 44 years ago. Only recently has it gone beyond the orbit of Pluto.... which is to say that it hasn't even really begun it's journey to other stars.
Voyager won't reach the nearest star for 16,000 years... and will, of course, not be functioning at that time. After the nearest star add another 28,000 years for the next star... and note, both of those stars are basically in our backyard compared to most stars.
To put it into perspective... Had Voyager launched when man first began acting like man "as we know man today" it would just today be reaching the closest stars.
Voyager isn't going to hit, much less land on, any stars/planets unless by near miraculous collision. It will have be very intelligent life to 'catch' voyager... far more capable in space travel than we are today.
I believe our only hope for 'contact' will come from some type of signal... radio waves, gamma waves, etc. But even that chance is remote... the universe isn't old enough, (theoretically), to have allowed intelligent life to advance to that level of tech ability and then also cross the vast distances of the universe, even at the speed of light.
