Not deliberate, no.

To me, saying that the clothes in ST ought to look "futuristic" is like arguing that they should not be speaking conventional modern English. It is certainly true that in 400 years, English will almost certainly be different in vocabulary and structure than it is today. But trying to predict what English will sound like in 400 years is a fool's errand, and there's a point where stylizing yourself in an attempt at plausible realism can actually turn off the aesthetic preferences of a large portion of the audience and thereby break verisimilitude. (Yes, that's right -- too much realism can be perceived as unrealistic.)
Better by far to just suspend our disbelief and accept that everyone's going to speak some version of contemporary English -- and that their fashion choices won't be too far from modern aesthetics either.
Or you could do what they did in Trek and have the language be a little heightened and unusual as a placeholder for future speak.
1) That is just as unrealistic as having them speak in modern English vernacular. Human beings will never always speak in prescriptivist language -- vernacular
always develops, because it is a fundamental mechanism for human bonding.
2) Using prescriptivist English in a context in which real people would not plausibly speak that way risks alienating a large portion of your audience. It signals a lack of emotional and psychological realism and makes it harder to emotionally connect with the character. I think it's worth considering that the most popular iteration of
Star Trek remains TOS, the version where only one character speaks prescriptivist English -- and he has a distinct character reason for doing so, since he's coded as neuroatypical. In fact, the most beloved characters who
do speak in this manner are ones who are coded as neuroatypical -- Data, Spock, Seven of Nine, etc.
3) The idea that speaking in formal, prescriptivist English is "heightened" or "elevated" is a classist idea, and
Star Trek should not support the idea that some varieties of English are "better" or "superior" to others if
Star Trek wants to support the ideals of equality and diversity.
Again, I don’t get how insane-looking aliens, time-travel, and floating macroviruses are hunky dory, but if people are not dressed in something out of the Sears catalogue, it’s too much.
No one has said that. But there's always a balance between stylization and not undermining verisimilitude by activating the audience's "camp" button. Imagination is good, but there is a such thing as becoming
so styilzed that most of the audience can no longer engage with the material.
