Having just finished a Trek TV series (DS9), I feel inspired to ask this question of other people: why do (or did) you watch Star Trek? Simply put, my primary reason (besides entertainment) for watching Star Trek is to see a vision of the future. To see Roddenberry-style optimism and ideology, but also to challenge and question it (as was done in DS9) is very important, because (in my opinion) the purpose of television is not only entertain us but also to inspire us to search for ways to turn that which we hope for into reality. As someone whose day job (as a scientist) directly contributes towards bringing into reality this more hopeful vision of the future, I'd say that Star Trek has been a pretty significant continuing inspiration for me, both personally and professionally. Trek's depiction of science (both the technobabble and its tendency to depict research as a largely individual effort, which is almost universally false these days) is deficient in many aspects, but in its ability to inspire people to take up research in the first place, it has been very successful in many cases. And that's not even considering the questions regarding morality and the human condition that are addressed to different extents (and sometimes very effectively) throughout each of the series. But that's just me, and maybe I take television too seriously. So I was curious as to what you guys think - why do you watch Star Trek?
