> Instead of parroting what you read on social media, how about doing a bit of critical thinking on this
Totally unnecessary. That gratuitous dig doesn't advance your argument at all.
> What about all the resources going into video games, sports, movies, music, amusements parks, television, weapons systems, desserts, travel and vacations, etc?
That doesn't seem like it's u/paxys issue to address. The person they responded to made a _very_ strong claim: "The single most important job humanity has is to get our eggs into more than one basket".
It seems entirely consistent with both the original argument and the reply that humans could have two very important jobs to address (climate change, and becoming multi-planetary) and still have resources to dedicate to all those other things you describe.
> Do you make the same tired comments when those industries are brought up?
I would make a similar argument that u/paxys made if the amusement park industry claimed that building amusement parks was the single most important job that humanity had. Similarly, for sports, video games movies, or most other industries. Claiming the mantle of "the most important job humanity has" is a very big claim.
> And that's not even getting into the fact that multiple things can be done by humanity at once.
u/paxys didn't say that we could only address one thing at a time. They were disagreeing with the claim that becoming multiplanetary is the single most important job humanity has. Disagreeing with which singular job we have is the "most important" one makes absolutely no claim as to how we should be dividing our time.
Ultimately, I actually agree with the original poster that becoming multiplanetary and multistellar is an important feat we should be aggressively perusing. But I also think surviving any extinction-event filters that may come along the way is equally important.
