“If anyone can summon cinematic spectacle with a few taps, what becomes of the place that once called it magic?“
That’s like saying anybody who got access to hollywoods cameras, sets, wardrobe and lights can make a movie. You need a story and the talent to tell it using these tools. Look at all the vids on YouTube. They all quite simple. None of them has an editor. ALL of them need one.
I'd say some 80% of videos on YouTube have some editing, the quickie short ones no. On one of my YouTube videos, I spent close to 80 hours editing it.
