Wow, this gives a reflection about our future. The nearest potentially habitable planet known is Proxima Centauri b, which orbits the red dwarf star Proxima Centauri about 4 light‑years from Earth (at least it is in a habitable zone of its star) [1]. So we don't have a choice actually except protecting and make sure our planet survives. That's regardless if it really would be able to support life as we know or not (probably not).

When I read stats like this I realize how stuck in this solar system we are. I wonder if billionaires would care for the planet more if they knew that Earth is honestly just it for humans, for maybe forever.

They're not going to be alive in 100 years (barring AGI intervention), so why would they care?

This. It's not a spatial problem, it's a temporal one. They are somewhat aware there will be nowhere to run to (I say somewhat because they still spend millions in luxury bunkers), they are just betting that it won't get really bad during their lifetime, maybe their kids lifetime for the more empathetic ones.

Not that we would literally do this with Voyager, but it makes me wonder at the potential utility of a string of probes, one sent every couple of [insert correct time interval, decades, centuries?], to effectively create a communication relay stretching out into deep space somewhere. My understanding with the Voyagers 1 and 2 is (a) they will run out of power before they would ever get far enough to benefit from a re…

Not useful, because the signal are too weak to be picked up probe to probe.

On earth, the tiny signal from Voyager at this distance is picked up by dish the size of a football field; same with sending of the signal.

Earlier quoted context omitted.

It gets even better when you think about all the damage we've done in ~200 years of industrial revolution. We can't keep our perfect home in working order after so little time but they believe we'll transform dead rocks with no atmospheres in paradise...

I’m not aware of any organisation or individual that has actual plans (backed with actual investment) for terraforming anything. This is a straw man argument.

Hmm, do you realize, that even if you have 1B probes everywhere. You're still bound by speed of light communication speed, right?

It's faster than probe speed in this age, yeah. But still not enough, if we're talking distances to other specific planets, stars, etc.

Two possible ways to solve this, humans will become immortal or speed of light bypass method will be discovered.

What if the probes carry smaller probes left behind at specific intervals that act as repeaters?

These baby probes could unfold a larger spiderweb antenna the size of a tennis court.
