This quote really resonated with me.
Vina : When dreams become more important than reality, you give up travel, building, creating. You even forget how to repair the machines left behind by your ancestors. You just sit, living and reliving other lives left behind in the thought record.
Could be anything, it's open-ended enough to allow the audience to fill in a blank instead of being preached at. Which isn't top say preaching is always bad, some issues are more universally repugnant than relatively so. If nothing else, and keep in mind I didn't dislike the speech in question, Tasha talking to Wesley about druuuuuuugs fits right into this. Only in a different way.
