For sure, I've been rolling my eyes at the Mars colony stuff for probably a decade or more now. I get that it's a fun futuristic thought experiment for nerds but the idea that Elon's going to send up some modern day Mayflower in the near future that builds a thriving settlement is obvious nonsense.
Well, the average person is so utterly illiterate in physics, science, and math that no, it's not obvious nonsense to them.
They don't really think through anything at all, because the human brain is hyperoptimized to not think, as thinking is energetically expensive, and even with that optimization to drastically reduce energy usage by just not using it, the brain still consumes a significant fraction of a human's energy budget.
We all have this problem. Even if you train for years to think "like a scientist" and critically analyze your beliefs and poke holes in the things you take for granted, you will always be vulnerable to ignoring something you shouldn't and missing something important.
I do get upset that people are so adverse to just doing some rough calculations about things. However, I've recently come to the conclusion that I just enjoy recreational math more than the average person. But I'm frustrated about all the people who sat next to me in math class saying "When will I ever use this?" and now going through their lives with zero literacy in math.
You had a chance to learn! To improve yourself! How could you squander that?! What else were you doing with that time? You were required to go to school for about 16 years, why didn't you just suck it up and make the most of that time?!
It hurts me how willfully ignorant people can be.
