I'm surprised to hear so many people suggest that VTTs add a lot of work for them. I'm not exactly tech savvy and it's so easy and convenient it would have set my teenage heart aflutter.
At the risk of confirming my priors, I think the shift from dungeons to more plotted, narrative adventures have made it harder. Dungeons were the killer app of D&D and, I think, one of the reasons it established and maintained dominance in the hobby. For most players, narrative adventures are more challenging to create, more intimidating (especially for new DMs), and more difficult to run (at least with a level of game-mastery that avoids turning them into railroads).
My take: Dungeons with some narrative context (see Phandelver) are the way, but we've lost our way. That said, this ain't a new problem, so maybe it's just something to get used to.
