You don't need AI to scan social media posts for wrongthink. AI may let you go deeper, detecting thoughtcrime based on certain patterns of otherwise acceptable speech. However, AI is already good enough for that and the sort of people who want this don't care about false positives (or really truth at all) and are probably already compiling lists. Historically these sorts of folks just make stuff up against their enemies if there is no real evidence, so I'm not sure AI does much at all here, except possibly adding some credibility for the less skeptical.
I see Mars as an inevitability. We need Mars. Our eggs are all in one basket and the only way to guarantee our future is to be a multi-planet species or to learn how to live in self-sustaining tin cans. Colonizing Mars would help us develop the tools for either one of these necessities. Colonizing Mars right now I'm a bit more skeptical about.
Mars is just a big dead rock really. The “self-sustaining tin cans” are the way to go IMO. We can learn how to do that in orbit around Earth (where aborting the mission isn’t automatic death), and then go colonize the asteroid belt, where the resources are just sitting there floating in space.
Mars offers: gravity, but the wrong amount. Air, but not enough. Sand and dust, but not the kind that grows anything, just the kind that gets in your filters. Also it is toxic. Not much magnetic field.
While habitats are definitely the way to go long term (planets are just sooo inefficient!), Mars still has some useful features: - while the atmosphere/graviti combination is a bit annyoing, the atmosphere still enables some nice propelantless manuevers (aerobraking, aerocapture, plane changes, etc.) - the gravity should enable reusable single-stage-to-orbit rockets with current technology, unlike on Earth - day length & atmosphere reduce the insane temperature swings you get on the moon (and no 14 day nights) and also makes the dust particles less sharp & thus safer - powered atmopsheric flight is possible (already demonstrated) - a lot of elements up for grabs bound in rocks & the atmosphere (carbon, oxygen, hydrogen, chlorine, iron,...) - two ready to use asteroid moons already in low Mars orbit - another body that could host a space elevator built with current materials
In the end all our eggs as in the same basket as long as the solar system, the galaxy or the universe would eventually disappear. Allowing billions of billions of human to live for the next thousands of year is quite irrelevant: nobody asked to be born, so nobody won't miss the opportunity. As for our legacy, 99.995% of us don't leave a trace meaningful enough to be remembered as individuals by our grand grand grand children.
So, OK to conquer Mars, but not at any cost because the ROI seems really low to me.
Gilgamesh went on a quest for immortality and lost it, the Pharaohs built grand monuments in their effort, which ended with their carefully-prepared bodies ground up in paint and medicine by Empire-building Brits and French.
Today the rich pray for the singularity and freeze their bodies. And want to colonize Mars I guess.
Vanitas.
I can see the appeal of "colonizing mars as an extinction-proof backup plan", but I'm not convinced that it's a positive-EV play. Attempting to go to mars increases odds of our survival in case of earth going to shit by some amount, but it also increases the odds of earth going to shit due to the waste, energy expenditure, and missed opportunity cost of not solving pressing issues.
Earth would have to go to shit by an unimaginable amount to be as bad as Mars already is.
