transporter room is complete waste of space. you can basically transport anyone from anywhere to anywhere so why the need for a transporter room?
What the hell else is O'Brien going to do, other than wait for Bajor to kick the Cardassians out of Terok Nor?
Plenty of things in that show....
"I don't know if I'd trust piloting the ship to a computer," when they had to pilot through an asteroid field full of radiation mines. (It was a TV-density asteroid belt. You could fly through an asteroid belt like ours blindfolded and not encounter anything more than dust, though a piece of dust at 50,000mph could be a problem.)
By the 24th century, that computer should be the most intelligent thing on the ship by a wide margin. A basic gravity-well navigation problem should be no problem.
Health care.
Very tiered levels of service. Senior officers get all kinds of extraordinary measures. Ensigns get a tricorder wave or a quick pulse check.
"
I'm not dead!"
Flat panels for controls. Oh god....touchscreens everywhere.
...
And why wouldn't Star Fleet keep a copy of all officers on file in the computer and merely reconstitute the dead? Picard dies fighting the Borg? No biggie, just rematerialize him from a backup.
Which they sort of did in one episode.
They always made a point throughout the show to make the human mind all special and such - no computer could possibly store or duplicate it.
Well, except for that one time...

Star Trek never was and never was meant to be
hard scifi. All their technologies are either there to set the tone of the setting or they're plot devices.

Something I read about the original series was that Gene Roddenberry wanted something kind of high-brow.
The TV executives wanted a western in space.
