The key phrase here is "current technology." If we stay on Earth then "current technology" in 100 or 200 hundred years will look much like "current technology" today, wrt space travel.Unless and until some new exotic physics is found to allow us to fold
space then there is nothing that we could possibly do to propel a
spacecraft fast enough to reach the nearest star in a timescale shorter
than a few thousand years. We could perhaps send out smaller faster
unmanned probes with a bit of cunning but I doubt if we could even get
to c/20 and c/100 might be a more realistic target.
The energy required to do that would still be truly astronomical and if
you add humans then the resources needed to make it self sufficient too.
No technology is going to allow us to reach the stars in a reasonable
time. And more to the point, no cultural change appears in the works
that would make it a human goal. Certainly not before we're extinct.

put Rutherford off further investigation of radiowaves as "unimportant". >>>
The only thing we know for sure is that our present standard model is
incomplete and struggles to reconcile gravity with the other forces.
Arguably, Kelvin wasn't far from wrong.
In a binary fence post error sort of way.

In a binary fence post error sort of way.What I'd say is that there's a good chance we now understand the
majority of the laws of the Universe. That we have a large jigsaw
puzzle that still has some missing pieces, but we have a good idea
what the general shapes of those pieces are, and the broad picture
isn't going to change. I don't think we're in for any major surprises
or upsets in our existing understanding. I doubt there will be any
holes at all in our knowledge of the fundamental laws of nature in a
century. Maybe less.
