I think there are a couple flaws in this design that seem to be glossed over. Granted the video was very long for this kind of topic so perhaps I missed the counterpoints. But, to me they are:

• the hoverpack negates the need to jump over everything, so the initial point is very early game focused, and in the early game you’re building simple things
• you should never really need a top down view of your factory to understand it. Manifolds are very simple, there isn’t a lot to figure out once it’s already built, and frankly if you build large, spaghetti factories then you need to do yourself a favor and simplify into smaller factories or rooms. Encapsulation is a friend
• coveyors on the ceiling are nice, but they have one fundamental flaw - you can’t see what’s on the belt. That removes your ability to assess flow rate or even to refresh your memory on what’s going where. I’ve done many ceiling conveyors and inevitably I end up hitting my head on the ceiling trying to peek at what’s going on up there

A better strategy, to my mind, is to use floors dedicated to conveyors, or have floors that are so simple that there are only two or three things being moved on the floor (except for floors with manufacturers and the like with 5+ things). It really improves the “readability” of a factory. Plus you can use windows and glass to still allow for glance value assessments if desired

Eh, there’s no tutorial here, people can make things the way they like

I like this enough that I’m glad I saw it before I got too far.
