Can't help but think of the Star Trek TOS episode where Kirk is accused of murder and they find the "murder victim" in the ship by identifying and isolating heart beats until they discover he must still be aboard. It's been almost 60 years since the episode came out, but still sorry if that's a spoiler

Classic Star Trek (speaking as a fan). They can scan an entire planet to find a lost crew member, but can’t tell how many people are on their own ship. And they have universal audio surveillance on the ship but still have to use wall intercoms.

The Star Trek series require a lot of suspension of disbelief, especially since in the years after it came out real life technology surpassed the stuff depicted in there. Like, in TNG people walking around with glorified e-readers but having to go to the big computer or to ask Alexa things instead of just tapping on their screens.

At least they got OLED style touch screens, and for a while it looked like everything would go that way but at least in cars some are going back to physical buttons.

In the new TV series Alien Earth, the low resolution CRT monitors and clunky keyboards aboard interstellar spacecraft really stand out. Presumably it's an homage to the 80s' movies.

Mostly im sure, but using older and simpler technology does have benefits when it is going to be used on ships traveling for decades at a time through space. Seemingly the mass of ships in the Alien universe doesn't seem to matter too much so chunky old tech that is easier to repair and hopefully more robust could make ships both cheaper and more likely to return from the apparently not uncommon ship disasters.
