It may be even worse, that different continent is on a different planet. Space(time) is absolutely, mind-boggling massive. Everyone knows it's big but it hard to comprehend how big and why there could be many alien civilizations out there capable of broadcasting or detecting but never intersect in any way because the detection windows of any 2 civilizations don't line up.

I remember reading somewhere that due to the differing pace of evolution and technology advancements, any intelligent living aliens we meet are almost certainly going to be gods or cavemen. I can't find the reference.

The article puts this in a confusing way, imho.

Habitable planets are the ultimate scarce resource. Once the earth is full we’ll have to find a way to move and there’s less than 5 good options in this solar system. In time they’ll be full too.
The only logical path is to download our brains onto computers, which will happen before that point. Once that technology exists, that's the only form of life that will dominate. Robots, nano-machines and hyper-intelligences will blow easily damaged flesh with finite lifespans. Habitable regions would be massively expanded.
What's staggering to me is that with the new Voyager discoveries lately it feels like we're a bunch of stellar savages who just managed to release a buoy far enough into the ocean to feel the currents. Let alone recognize another savage on a different continent who might be doing the same experiment.

Are we though? Universe is huge. Wars on earth are waged over scares resources. If we are capable of reaching aliens would we really be incentivized to fight them while there are so many resources available elsewhere?

Second, what does 'earth is full' even mean? We have vast swaths of 'useless' land, like arctic and desert. Cities/towns/anything cover like 1% of the world. It is easier to desalinate water / build cities and greenhouses in deserts than it is to move people to another planet. We could host a lot more people if we adopted some serious geoengineering and built greenhouses /ate less meat.
Thirdly, travel to another star system requires insane amounts of energy, and could only be done by civilisations that already have enormous space infrastructure and industry. In which case you build habitats like we build skyscrapers, you can terraform, etc. In that case you don't need or want to ship billions of people to another star system.

Given the relative age of planets and stars, other alien "civilizations" would be hundreds of millions or Billions of years older than us. The notion that we'd all be roughly at the same level of advancement is statistically impossible pop-sci-fi fantasy. In my opinion, it's unlikely that they are even organic individuals anymore. Even the separate alien "entities" might have a process of merging once they achieve a…
Maybe the fungi think that about us? They've been around longer than we have and take up more of the planet.

The article is just poorly written. Even the first line is messed up... > Those 1,004 star systems are in a direct line of sight to our planet... It's SPACE. Every star within 1000 light years is in a direct line of sight to every other star.
> Every star within 1000 light years is in a direct line of sight to every other star.
There could be space crap in between. - Of course I just realized something obvious. Along our PotE lies most of our solar system debris. Shouldn't that be obstructing alien views?
Excepting highly tilted orbits or unusually clean solar systems, how are we seeing exoplanets at all? Is there a sweet spot, just a bit above the plane, where observable solar occlusion still occurs?

That’s why the best thing any species can do for the other species is to leave signs that we were once here.
I know it sounds depressing but I keep getting reminded of this [0] when thinking of loneliness in the universe. It's the most apt description I came across in recent memory.
