In The Original Series in the 60s, people had no idea what the future would look like or what technology would look like. In one of the early episodes, they had a paper print out machine on the bridge that looked like a fax machine, which was considered futuristic in the 1960s.
Like the example of the Enterprise fax machine, what technology or system do you think are we displaying in the current Star Trek shows that will show how dated we will become in the future?
If I remember correctly the original designer’s ideas were that the nacelles were meant to be dangerous to be around, so they had to be separated from crewed areas, the saucer section was supposed to be a habitable life-boat in case of emergency, and the lower body was for mass storage, cargo, and main engineering. But over time startship design has ignored most of these concerns. In-universe I guess you could say nacelles got better shielding, replicators got better, so there was less need for space for non-reconstitutible cargo.
