VR has a long way to go on the technical side, but true blacks and latency are both basically solved. Vision Pros have a motion to photon latency of ~12ms, which is unnoticeable, and miniLED and OLED allow for true blacks in plenty of headsets. Depth-of-field hasn't been solved yet, but it is doable. Processing power and battery are limitations, but not critically so.

IMO, none of those things are major factors compared to how insanely clunky current VR headsets are. That's where the real fundamental issues show up-these headsets need to lose ~90% of their weight and size before they'll catch on.
