Technobabble in Star Trek is a definite problem. If anything, I'd actually say its overwhelmingly the worst problem the franchise has. I think especially to newcomers. A good rule of thumb when looking at technobabble is to examine the vocabulary of the show.
Some examples from TOS: Warp Drive, Communicator, Deflector Screens, Phasers, Photon Torpedo, Tricorder, Duotronics, Dilithium. Perform a small thought experiment for me if you will. Imagine explaining what all of those words mean to someone who has never watched Star Trek, but is vaguely aware of it. I'm betting the majority of people will get tripped up by the Photon Torpedo being a matter/antimatter weapon because the question then comes up "Why is it called a 'photon' torpedo then?" and I can guarentee that everyone will get tripped up by Duotronics. That one I slipped in because the term is actually meaningless and never properly explained in the show. The best you can do is tell someone its a really fast computer. Unless you crack open a technical manual, but if you do that you're already lost the interest and probably pateince of whoever you're talking to. Same with Dilithium.
TOS was this way because audiences back then didn't have a lot of patience for bullshit. In a lot of way the 60s was very matter of fact when it came to things, and stuff like The Twilight Zone had to frame its mysticism with an element of horror or as a thought experiment to compel people. So all of TOS's technobabble had to be easily related and explained. What's a communicator? Oh, its like a radio. What's a phaser? Oh, its like a laser beam. What's warp drive? Oh, it lets the ship travel really fast. Etc.
Jump four movies ahead and look at TNG, which was really the start of where this was breaking the hell down and kind of never really stopped. You get words like multi-dimensional, multiphasic, multispectral, tachyon, particles, trilithium, etc started just getting thrown around willy nilly. It also unleashed the plague of warp plasma on the franchise which technically has a scientific basis but gets treated like magic space dust. The average TV viewer can't tell you what a tachyon is, and even the average Star Trek fan can't tell you why a cloaking device emits them as exhaust.
This peaked in Voyager where some of the lines are just pure word salad. I'm wondering if the writers had some kind of ongoing contest about who could insert the most idiotic and convoluted technobabble into the scripts. Enterprise tried to do damage control on that to some extent but I think they failed horribly. If anything, the vocbulary of Enterprise should have been more down to earth than TOS. We should have been hearing words like nuclear, rocket, armor, missile, fission, fusion, laser etc because Enterprise is closer to our real world technology. Instead they stuck with a bunch of the technical terms from the other series.
