To be honest this is one of the more real proposals I've seen for an Interstellar probe, and there are still many problems to be worked out as both the paper and the comments here point out.
I admire the optimism in the paper though, even if its misplaced. Maybe pooling together resources in the scientific and engineering communities to develop an interstellar probe system could give a working result, but there are some significant hurdles to overcome first. It would be a big project, taking many years to see fruition, but at the same time it could also be a game-changing development and a hugely inspiring feat.
Could we see probes in other star systems by 2075? I think its not an unreasonable suggestion.
