That's certainly true to an extent. Other commenters have already highlighted necessary complexities. There is absolutely a lot of very entrenched "ways-of-working" that add unnecessary complexity, as with every domain. Not everything is a technical problem though and the social / process side of this sort of setup is what can make it work at all.

The approach that you're hinting mostly describes the general direction of remote production (https://video.matrox.com/en/media/guides-articles/what-is-re...). The big traditional players are already across that (https://www.grassvalley.com/ampp/, https://www.rossvideo.com/use-cases/remote-production/), AWS also has a plethora of services to lock you into their stack (https://aws.amazon.com/media-services/), and there's interesting new players too (https://www.tryiris.ai). There's a heap of different workflows out there, and OB trucks like the one highlighted here are just one of those.
