Wrong, Harry Kim said it.
What Kim knows in his vernacular as a "replicator" is far advanced and refined beyond what Kirk knew in his as a "food synthesizer," which in turn was more advanced than what Archer knew in his as a "protein resequencer," and Kim wouldn't call one the other. Similarly, a "holodeck" is a specific type of facility that meets a certain 24th-century Starfleet standard. It's a virtual science lab, combat simulator, and recreational amenity for the crew
all in one, equally equipped and effective for any of these purposes on verbal command. Starfleet ships of the latter 24th century come stock with this type of facility. In the 23rd (or at least in the 2290s) they didn't. But that doesn't mean that various Starfleet ships mightn't have had holographic/VR tech of various sorts for various purposes that would only later come to be refined and integrated as what Harry Kim knows as a holodeck. On the contrary, we've seen that this is indeed the case.
Replicators cause matter to materialize out of thin air. If the food processors work that way in TOS, why are these tribbles there?
Per Scotty, they probably got in there the same way that thin air did: "through one of the air vents"!
No they're not, they're called food slots.
They were never called that in dialogue TOS. They were referred to most frequently as "food synthesizers" and also once or twice as "food processors."
Enterprise had protein re-sequencers though (not synthesizers like I said before, oops)
Enterprise also had a chef. The Re-sequencers were probably for quick meals, small things.
Yep.
"Breaking The Ice" (ENT)...
ARCHER: For the most part, the same things you eat at home. Our chef can make anything from a peanut butter and jelly sandwich to turkey with all the trimmings. We have a hydroponic greenhouse on board where we grow fruits and vegetables, and we can also replicate certain foods with our protein resequencer.
"Dead Stop" (ENT)...
T'POL: A matter energy converter...I believe it's a molecular synthesizer of some kind, similar to a protein resequencer, but far more advanced...I saw a similar device on a Tarkalean vessel. It was capable of replicating almost any inanimate object.
Have they actually called the devices in Discovery replicators?
Nope.
We also very specifically saw how bad the visual acuity of a visor was, a 20% reduction off that would be near blind.
And that was 100 years more advanced then anything that would be seen here.
With the VISOR, Geordi could "see" much
more of the EM spectrum than he could have with healthy human eyes, from all the way down to 1 hertz all the way up to 100,000 terahertz, all processed/converted/compressed in real time to avoid sensory overload of his visual cortex.
That's the range the 20% would be shaved off, and maybe Geordi really valued that 20%...or perhaps he was just a bit emotionally attached to the VISOR as part of his identity, having never seen via any other means. Pulaski also emphasized that there would be no going back and reversing the procedure if he didn't like the results. That would certainly tend to give one pause.
But/and/or if his later decision to opt for ocular implants was due more to technological advance in that field than his own personal growth of confidence, then surely that/those breakthrough(s) occurred at some point
after TNG, not before. Maybe there had not been any significant leap forward in artificial eyes for more than a hundred years at the point he refused. Not every technology advances smoothly over time with steady and uninterrupted progress; some spurt and stutter, reaching several sequential plateaus before achieving a "peak," which with time may prove just another temporary plateau, and so on.
With the forcefields, replicators, Tthe holograms and now the holodeck, they've basically reconned all 24th century technology into the pre-TOS 23rd.
This was no retcon on DSC's part. ENT already had more primitive versions of them in the 22nd. And as to how much of a retcon
that was to begin with...let's just say it's been a tad overstated at times.
Not seeing the problems others are with any of this, to be honest.
