The big problems before were a combination of software, cpu/graphics potential, and connectivity/bandwidth. Certainly the software has matured in the decade(s) since the initial hype but I don't know how many currently have adequate devices and connectivity to make it work on scale. I think AR has a chance at a foothold (still opportunities to fake cutting edge with some smoke and mirrors) but VR? I dunno.
