Access to reliable tech and infrastructure seems to be a big stumbling block. VR doesn't solve some of the more fundamental issues, like students not having reliable equipment and Internet connections, or the backend not being able to support the demand (whether in terms of volume or flexibility to different teaching requirements).
I personally do not think its a lack of high tech. A written schedule mailed every week and the ability to email or call the teacher once or twice a week would get you 90% of the value.
That is pretty much what they are doing right now in my state. Packets can be downloaded every two weeks, or picked up if they do not have access. Teacher does a zoom with the class a minimum of twice a week.
But with everyone WFH, making time to work with and teach your kids is difficult. At least young students..
