I keep seeing people coming up with arguments that sending shuttles in orbit is a waste of ressources, worsening the polluton problem, that these amounts should be used for famine and poverty.
But I don't get if these detractors see in the long term where there is clearly an advantage for that for human specie survival.
The Earth has been existing for about 4,5 billions years and the Sun will become a Giant Red in about 5.4 billions years and the temperature of the solar system will increase drastically and the Earth matter will heat up and it will evaporate. This will sign the end of the human race.
Even if we only colonized Mars at that point, we will still be in a bad situation, because Mars will also evaporate.
There is 2 options if we wanna see humanity thrive,
Either we create a general AI that can travel through interstellar travel without need for life support like oxygen or food so it will reach Proxima Centauri in the next 4243 years and navigate for another biology-hostile planet to colonize it with a cyborg AI made by human.
Or you can send a replicating machine that finds an Earth-like planet and then starts a new phase to the human race with a yet to be engineered 3D printing machine that assemble a colony of humans to preserve the billions years of evolution that brought us humans and avoid wasting all that complexity formation.
The other option is we don't do anything and we disappear with our sun.
Are we going to sink with our ship or navigate to find new ones.
Which one would you rather see happening?
