Agree. Voyager is probably considered by many to be one of our greatest achievements.

It makes me wonder when we'll have anything set foot in another star system. I would guess realistically after 2100, but then we went from the Wright brothers to landing on the moon in under 70 years... so I may be proven wrong.

Space is so ridiculously big that I don't think it will ever happen.

Back of the envelope math - 4.2 light years to the nearest star that's not the sun, current vehicles traveling about 10x the speed of voyager (e.g. 1 light day in 5 years). If something was launched today it would get to the nearest star system in about 7,660 years (assuming that star system also a radius of 1 light day).

100x faster than current (1,000km/s) would still take 76 years.

Definitely not before 2100 and almost certainly so long after that we will seem like a primitive civilization compared to those that do it.
