Sci-fi does great things to inspire people but inspired people have to educate themselves beyond the Star Trek to see what the real trek would even be like. They just hand-wave and say things like "technology is evolution" like somehow that makes a Mars base happen because reasons.
Hmm. Mars enthusiasts have to "educate themselves", you say. Can you tell me what the Sabatier reaction is, and what implications it has for in-situ resource utilization on Mars? Can you tell me how the radiation risk on Mars compares to that of, say, the Apollo missions or just living in a high-radiation environment like that of Colorado? How about we discuss the Linear-No-Threshold radiation risk model and whether it's a valid assumption? How about you expound for a bit on the Oberth Effect and how it impacts Delta-V requirements?
I'm far from an expert on spaceflight, but I have read a number of technical books on the topic, taken university courses, and attended a conference devoted to the question of Mars colonization. So, please do yourself a favor and read up on the REAL technical difficulties that exist with respect to human spaceflight, and don't randomly accuse people of being pie-in-the-sky Star Trek fans with no grounding in reality. There are lots of interesting questions to discuss and nobody thinks that interplanetary colonization will be easy, but human exploration has always occurred at the very limits of our technological capability.
If you have some real technical objections to human spaceflight, it would be interesting and useful to discuss them, but at this point it sounds like you're expounding about something that you haven't really taken the time to understand. The real thing I want to find out: how does supplying air for a modern space traveler with modern technology compare, in terms of actual difficulty, to supplying food for an colonist using colonial-era technology? I would much rather put my trust in the former than the latter, and it seems clear to me that the challenge is fundamentally the same in both cases: the application of technology to sustain human life away from major social infrastructure.
