Jup that's quite the concern I have too. Although I can't help but imagine there's some things we'd still like to do irl.
But if the vast majority disregards real life that could get messed up. It's not here in a week though so I think we'll have time to cope and adjust :-)
Think it's going to be bad no matter how you slice it. It will take off, and the masses will get hooked to it in a few years to a decade. The more I think about it, the more I feel like Ready Player One was a documentary about our imminent future rather than a sci-fi.
