All languages? Yeah, even for Star Trek that strikes me as impossible.
I would have liked to have seen star trek finally indulge a bit of post-humanism (human being a relative term in this case).
Over and over again Star Trek's science advances have shown no real effect on quality of life that we can see. Yes you can take a pill and grow a new kidney, but the human life span does not seem to be THAT much longer than it is now. Decades longer, not factors of magnitude.
You can make a replicator that can LITERALLY make anything out of literal shit, but the best recipes are restricted to higher ranking people. Is good food some extra downloadable content you have to pay for with the money that may or may not exist?
People don't appear to have increased brain capacity judging by some of the stupid decisions that get made, nor do they seem to learn from previous past lessons when they keep doing the same things all over again.
We're made to believe, except in the rare instance of Dr. Bashir, and the counter-opinions of the Denobulons that tampering with genomes is a very bad idea and leads to villains and dictators.
After over a millennia of being able to build full holographic and virtual worlds, why don't entire populations just live in them?
I know, star trek never makes a lot of sense, but they do keep missing the chance to actually put some science in science fiction. Let the 32nd century finally be a different place.
