It was a cool project but a waste of time due to the mathematical odds against success. Perhaps if they discover an earth like planet they can dust off something like this concept with a target in mind.
They just have come up with an earth-like planet about 45 light years away. What that means is that if you scale the universe to make the distance from here to Mars about a foot or thereabouts, the planet just discovered would be 45 miles away. That’s the difference between distances inside our own system and interstellar distances.
