The writer's conclusion is that we Humans will progress to the point that we won't care to travel to other stars, and that other species have likely evolved to the same state. I'd suggest that the first part is likely correct. We will progress to the point that we have access to all the information and Human opinions that might interest us and, thus would allow us to travel to the stars. However, whether or not we're interested might be much less important than the issue of latency. If we're all connected, traveling much past the Moon will cut us off from the "hive mind" in such a way that we'd be so lost as to no longer be functional, due to the delay in exchange of information due to the finite speed of light. This isn't an original thought. The late, great space scientist, philosopher, and SciFi writer Charles Sheffield made this exact point in his short story "Power Failure", which I read in his 1979 collection known as "Vectors". It is the single most thought-provoking SciFi collection I've read.
