Look I like a good science fiction novel too, but is is pure escapism.
I prefer to believe that we have much to learn about physics that may entirely change the way we look at problems.
That space probe would take 80K years to get to the nearest star and it was launched in the '70s. 54 years for a probe launched in 2020 would be a heck of a log-log curve.
You suffer from limited vision, and a fixation on current methods for solving problems.
There are companies writing software for computers that haven't been built yet, because the statistical probability of the computer being available when the software is finished is so high, and so well recognized (Moore's Law).
The human genome program was started well before there was any possibility of it being finished in a human lifetime.
You can read how that worked out with modern DNA sequencing.
Progress is made by dreamers, not the ones that say it can't be done.
