Am I reading something into this?
Is he hinting at something?
What’s most frustrating about the U.F.O.s story is that it obscures the fact that scientists like me and my colleagues are on the threshold of gathering data that may be relevant to the existence of intelligent extraterrestrial life. But this evidence involves subtle findings about phenomena far away in the galaxy — not sensational findings just a few miles away in our own atmosphere.
Powerful telescopes that will soon be operational may be capable of detecting city lights on the night side of planets that orbit distant stars or the telltale mark of reflected light from planet-wide solar-collecting arrays or the distinctive sign of industrial chemicals in a planet’s atmosphere. All of these “technosignatures,” should we find evidence of them, will be small effects. If we do detect such things, you better believe that my colleagues and I will go to extraordinary lengths to eliminate every possible source of error and every possible alternative explanation. This will take time and careful effort.
