First off, your assumption that "it [VR] is becoming evident that this is the future of computing" is not necessarily true. We have no idea what the future of technology is (obviously) and if I were to take a guess, VR would not be it!
BUT if we decide to accept that VR is the way to go and take everything in this scenario as fact, the biggest effect on society would be the fact that 7/10 of the population is dead. Generations later, history books would tell of the "VR days", "When 70% of humanity was annihilated by computers strapped to their spines".
No I don't think we would shun technology. Think of the US... We get in wars all the freaking time and don't mind guns. New Orleans gets massive floods if a hurricane hits just the right wasway but Cajuns don't move. The point being: eventually people would come to realize that doing away with tech isn't the answer, but using it responsibly ISis.
