FTL communication of any kind disrupts causality as we understand it. It's likely not possible. The article is wild speculation, but so is everything regarding aliens. Even educated guesses are really just wild speculation because there are too many unknowns. We don't even know how many worlds can support life, how many forms life can take, how often life might evolve intelligence, etc. I wonder sometimes if maybe there's a easter egg hidden in physics. If there were an easy way to convert matter to energy that we have yet to discover, we will likely destroy ourselves once we discover it. All it would take is one psycho with the right resources to unleash a kind of devastation that would make nuclear weapons look like fireworks. There might be no intelligent life out there because discovering the kind of energy resource that allows for easy interstellar travel might also make it too easy to kill ourselves. Another possibility is the end game of intelligent life is not travelling around 21st century style, but digitizing our consciousness and living in a virtual world. Why travel to the stars when it makes more sense to turtle up in a giant computer and enjoy life? Something like a Dyson sphere. Another possibility is the aliens are out there, they've just perfected the invisibility cloaks we're currently working on. Star Trek style, they're monitoring us unseen so as not to interfere with our civilization. It's fun to think about, but it's all wild speculation at this point.
