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?
I’ve got one better: in at least one if not two instances, Spock uses an E6B flight computer (a specialized aviation slide rule, WWII technology) to calculate a time of arrival/impact problem. They’re still made and sold today for student pilots but they’re definitely outmoded.
