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?
The choice of drugs. Star Trek is all about alcohol (often alien alcohol) and caffeine (sometimes alien coffee). Any time any other drug is shown / mentioned, it's because it's a big enough problem to be a plot point. I think 20 years from now, a few light drugs, including marijuana, will be so common that it will seem strange that they're not part of society in the 23rd century.
Good one and a great point .... our current attitudes about mind altering substances will be looked at in a very different way in the future ... whether that will be a good or bad thing, I don't know ... but I do know it will be far different than how we see it today.
They'll see us smoking, drinking or ingesting all kinds of weird cocktails of substances, like alcohol, tobacco, marijuana or any of the legal and illegal drugs we have today and future generations will see us as just ignorant teenagers who found the medicine cabinet and the liquor store.
