Wow “proven wrong” is a big word to use, nobody proved anything around here. And lets not get pumpous or fanboyish or even childish, my arguments are valid here and I know a thing or two about it that gives me that re-assurance.
Again this does not mean in any way that UE4 is sub par engine on the contrary it is not, it is a world leading enigne. Only don’t judge an engine which is primarily focused for the video game industry based on film industry standards.
We are not there yet. UE5 maybe just maybe will start this process to a limited extent and I can see how it might be used in backdrops and in other elements such as mattes and compositing specific things with Nanite driving those meshes on import without the need to optimise them and Lumen avoiding bakes and giving good enough GI to make it fast and workable out of the box.
But please lets stop the bullsh*t and start reading carefully.
Edit: Funny enough this reminds me of the argument that went on for so long on how UE4 UI was a bloated mess and needs to be more streamlined and more minimalistic, I wrote this almost 5 years ago and got bashed for it here, most everybody LOVED the UI in UE4 and told me strictly that I should not even bring up Unity’s UI as an example of minimalism. I wonder what they are saying now when the new UE5 UI is looking almost exactly the way we had wanted it to look 5 years ago and ironically closer to Unity’s UI.
How interesting.
I think the next thing will be making the mouse pan inverted as default to match every other 3d package out there. Maybe we’ll see that in UE6 
Edit02: It is not wrong to critisize anything to want to make it better, I want UE4 to be the best out there so that our lives in development can be more fluent, this is why we have these conversations.
