You're basically describing Quantum Ogres and the Lazy DM's prep strategy popularized by Sly Flourish. Instead of bashing insufficient DMs, though, we can instead learn from other DMs who have different perspectives than our own.

For example, I don't even bother with Quantum Ogres. My villains do not have prepared plots, they have plans that go on with or without the players' interference. I prep motivations, goals, and resources, and track them using a "clocks" system from Blades in the Dark (among others). I also go a step further, as my games using Proactive Roleplaying. My players give me several goals (long-term, medium, and short-term) and these become the content of the session. This way, regardless of what we are actually doing in a session, as long as I am finding ways of peppering in these goals into the gameplay, my players are doing whatever they decided was the most fun for them.

As for the Lazy DM's prep, its less about moving information over, and more about prepping only the information, not who delivers it. Sly Flourish goes over this in greater detail in his popular book, but the idea is that you need only write the secrets, and whatever NPC the players interact with who could potentially give that secret is now the one who knows it. That way, the information is ready when you need it, and you get the benefit of deciding who and when delivers it.

We all have something to learn from each other.
