The more I think about it, the more I'm convinced that #StarTrek has those Vulcans (or Data) to convince you not to look into the logic of plot/people.
"There's a Vulcan around, if they can't find a fault in that logic, neither will I!"
Hard #SciFi doesn't need cheap tricks like that, because there's (hopefully) no gaping flaws?
"Western in Space"-Starwars doesn't need it, because nobody expects any logic. (not even from droids)
And even grimderp WH40K doesn't need such things, because why would there be logical plot if there's literal multiple chaos dieties around? (still better plot/science than Star Trek - because the rules lawyers couldn't stand really bad flaws)
Only Star Trek likes to look like it's science based, when in reality it's rather "rule of cool"-based and only "teching the tech". There's no need for Science if you can substitute with #technobabble. There's no need for complex plot, if you can just have superhuman main characters win fist fights against people "five times as strong as a human" all the time.
Time travel? We do it permanently! It's not like that one crushed car would change the future in any way!
Who does Science? There's some shady science org that does build a groundbreaking new fusion plant in the same building it's holding their (currently child aged) genetic engineered super humans! (who will take over mankind soon)
