'Technobabble' originated with episodes of Star Trek where there would be cues to "insert technobabble" in the script where the episode required believable dialogue based upon the science/utility of the future tech that specific staff writers would fulfill. And unlike Star Wars, Star Trek was quite a bit more scientifically accurate (many real world technological advancements were envisioned within ST's many episodes). The term often gets wrongly attributed as being 'nonsense speak', but is generally well written jargon that contains enough 'real world' science so as to seem plausible. 'Technobabble' isn't shorthand for scientific ignorance, it just signifies a requirement to fill in the scientific/technological gaps that the writers originally left out.
Star Treks 'technobabble' was actually written into the show, whereas most of it in Star Wars is after-the-fact and generally a cannonization of adopted fan theories. Virtually none of the 'reality aligned' science in Star Wars is there at the writing phase. It comes much later in EU stuff, or the many guidebooks that are published later. The mechanics of how any thing works in the world of Star Wars is deliberately left vague at best and mostly non-existant (and I'm specifically talking about the movies, animation and TV shows - the novels and comics do occassionally give a touch of depth). It's only suplemental material, fan theories and headcannon that provide any substantial explanation to 'how things work'.
Just wait, one will exist to make any current and future use of lightsabers as cannon as Wookie Life Day!
I'm neither disingenuous or a troll, and I am a much bigger fan of Star Wars than I am of Star Trek, despite how the above may come across! I've just learned that I appreciate Star Wars more if it's not taken too seriously. I like the fact that you can be a fan of the same IP as me and yet we can debate how our interactions with it differ. Like the fact that you seem to only accept the nonsense of the franchise if/when an unconnected writer specifies the problematic mechanics of a story told by someone else enabling it to make a reality aligned sense to you, whereas I just want to get swept away by a fantastical journey into a realm that's undecipherable from our own.
I don't care about how plausible the science of a make believe world that's populated with aliens and magic is, but break the main story of the franchise by bringing back a character whose death was central to the arc of the major characters of the first two trilogies and I'll be pissed.
...and it's fine by me if you don't want to acknowledge the other times I pointed out, pre-High Republic, that lightsabers were used in a similar fashion because it doesn't sit well with your unmoveable view of everything High Republic.
