I apologize for coming in late. Some topics take off so fast casual users like me can't keep up. I didn't read the entire thread, so if this dredges up some battle that's already been settled, I beg your forgiveness. This leaped out at me and begged support and elaboration.
I can't really add much to this. Pretty much nails it, for the practical underpinnings.
I would like to add some more justification.
Let's remind ourselves of Clarke's Third Law

Any sufficiently advanced technology is indistinguishable from magic. We live in a real world saturated by ubiquitous technology. Everything has electronics in it. Even your car key has a microchip in it. Your dog probably has a microchip in it. There's RF flying about all over the place. Both the dog's and the key's chips, for example, wake up when a handheld scanner sends a radio signal asking, "Are you there?" The chip powers itself by soaking up that RF, so it can reply, "Yep." Then a more complicated machine conversation takes place.
We take it for granted, don't even notice it. To a person from even 100 years ago,
we are living in a Potterverse! Touch the screen of a pocket-sized instrument, and within minutes a man bearing a pizza will ring your doorbell.
When you think about it in those terms, D&D 5e's magic isn't at all surprising. The game assumes we're playing in worlds where magic takes the place of technology. Magic is what heals injuries, not sutures. A CAT scanner will never even be developed, because you don't
need technological diagnosis techniques when you can just cast
cure wounds. You don't need cheap, disposable crap from developing nations, because you can take that heirloom vase you just broke to the hedge wizard to have
mending cast on it. These are worlds where there will never be an Industrial Revolution,
because with magic there is no need for technology.
I've been playing this game since casting your one spell and cowering behind the Fighter is how you spent an evening. Things move on. I don't think that's "ruining" the game by "Potterfying" it. It's just how it is. It's different. If you don't like that, fine; use the optional rules for the gritty, R E Howard feel you want or ditch 5e altogether and go full grognard.
Anyway, them's mah thots. Thanks for letting me vent them.
