Wow! If I had a nickel for every time a Trek show had a blind engineer, I'd have two nickels. Which isn't a lot, but it's weird that it happened twice. Right?

It's crazy that the entire engineering section on Starfleet ships is just right next to the warp core, with absolutely zero structural separation.
The number of times ships had to eject their warp core, or had the warp core go critical, or had other warp core related accidents, you'd think Starfleet would have learned not to exclusively rely on emergency force fields and that they would have simply built two separate sections for engineering and for the warp core.
But no, even after all those experiences, they instead even ditched the isolation doors when they designed the Intrepid class, and basically wrapped the engineering section around the open warp core.
Cause what could possibly go wrong with that approach, eh?
I feel like they do that all the time throughout the TNG era, owing to the fact that they didn't have a "science lab" set in addition to the warp core set which at any rate looked cool and they wanted to use it whenever they could.
Geordi started as the blind navigator, for irony. They moved him to engineering in season 2 when they decided the did need a chief engineer as a regular character, and Wesley could serve as helmsman.
I don't know if Geordi would describe vision with his VISOR as "better", just that it allows him to see more of the E.M. spectrum. The few times he gets to see with natural eyes (when Riker's Q powers restored his eyes, and when the magic immortality planet "healed" him) he describes seeing beauty that he normally isn't capable of experiencing. "Better" is always subjective
He was just a mycology engineer, not the chief engineer. I honestly can't remember if we ever see main engineering on Discovery. They mostly work in the Spore Drive engine room. But that was Discovery's schtick, that it wasn't the "main" crew that were the stars originally.
'Hi we're Starfleet, and we recruit our captains from among the best and the brightest on 150 member worlds, spread over 8,000 light years! But the vast majority of the time, when it's not Jean-Luc Picard, we just get them from this one particular country that accounts for about 4% of the population of Earth. Weird, huh?'
If they were smart, they’d bring back Hemmer in the first episode of season three. Having him on one of the Gorn ships would be a perfect entryway for the storyline.
