I think there are a couple treknologies that exist now, or at least are pretty close. The translator tech is not very far ahead of what we have today. The communicator actually influenced the design of early cell phones. Trek predicted quite a few real life technologies. I definitely think something similar to the replicators will exist eventually, hell 3D printing food already exists.

In terms of the more out there treknologies, I think the gene editing that is illegal in the federation is pretty scientifically grounded. I also think the medical tricorder will some day inspire/shape new tech similar to the communicator with cell phones.

Future shock: 11 technologies that science fiction predicted

Who knows what the future might hold? Science fiction writers do, it seems. Some of the most outlandish scenarios imagined by writers of films, TV shows, and books have come true, and they were actually inspired by science fiction. In fact, without writers to imagine them, digital technologies such as video chatting, cell phones and tablets, drones, and robots might not even exist.

The translator tech is not very far ahead of what we have today.

I would disagree with the translator. On the surface, yes, but it is incredibly far removed from how any of our translation technologies work.

The universal translator works by scanning your mind/brain signals, finding universal constants within it, and then constructs a translation that way. In theory, a novel alien could be parked next to a universal translator, and it would still be possible to translate for them, in the absence of a linguistic database.

I also think the medical tricorder will some day inspire/shape new tech similar to the communicator with cell phones.

It sort of has, but more in the other way, where the devices are inspired off its functions instead of its form. Going off of wikipedia, there’s some speculations that a smartphone might well become our equivalent of a tricorder thanks to the massive amount of sensors that they have in them.
