Apart the therapist and style, those are allegories of (then) modern stuff. That is obviously absolutely fine.They had a therapist on the bridge, had a secretive evil empire enemy hidden behind a big space wall and their biggest threat was cyborg technology run amok. They couldn't have been more late 80s if they tried. That's before we even get to the design and the hair.
Of course any fiction is inevitably product of its time to certain degree. But they intentionally tried to portray the future humans different than modern humans, and I think they succeeded pretty well.They were certainly trying to portray an evolved future human race, I don't deny that, but what they ended up with was an eighties vision of the future.
I love TNG, it was my Star Trek, and it has a holistic consistency to its visual world building which I think is brilliant (you know what you're watching from a single frame), but it is as much a product of its time as any Sci-fi, and perhaps even more so for trying not to be.
