Of course it can replicate existing workflows and show existing content. The exciting potential of this class of device lies in the immersive experiences that exist only as demos. This is content that must be tailor-made for VR/AR/XR. Honestly, I own a Quest 2, and I barely use it. Not because of the resolution, but because the immersive content just isn’t there. There are demos, but nothing I can sink my teeth into. Apple is in a prime position to change that, it they don’t really even acknowledge the problem.
