It used to be cliche for the scientists to be warning/screaming about pending problems or solutions until the crisis forced people to listen to them and finally solve the crisis. Far too often, with the scientists aiding the meat-head protagonist with the fruits of their labor to safe the day as the promoted hero and if they are lucky they live to the ending and get to make an appearance at the conclusion. Too realistically, the protagonist is a maverick who breaks the norms by listening to the scientists; both being held back by politics in addition to the problem needing solving.
The liberal biases are not intentional, it's just that conservatives are usually irrationally, in the way because by definition, they cling to the status quo. Reality does not align itself to our tiny minds which is why it appears to have a liberal bias as we adapt to it.
Sci-Fi today means anything in the future, involving space, time, etc. it used to involve science or at least scientists. If it is just a MacGuffin does that make it Sci-Fi? Are Indiana Jones 4-5 Sci-Fi films?
