Moore's Law actually predicted a doubling every two years (for CPUs), not every year, and even the very optimistic Kryder's Law (often cited as the version of Moore's Law for storage) only claimed an increase of 40% per year. Actual progress has fallen far short of that. The rate for 2010-2014 was only 15%/year.
Rates were quicker back around 2000-2005, but that pace has fallen dramatically.
I think it is reasonable to expect storage to jump dramatically at such a time that we begin storing “3D” data. Not that everything in VR will be voxels or anything, but even if the fractal dimension of our future data is 2.5 it would obliterate our current needs for storage. /speculation
