Interesting point,
I wonder what is technologically feasible (and cost effective) these days - just how fast could we actually send something out ?
Is there an upper limit to using gravitational slingshots or could we just use raw rocket power to accelerate them faster ?
This could literally be the next Space Race ! - which country (or company) will send out a new interstellar spacecraft that can overtake the Voyagers !
