This is not going to change the rural/urban dynamic because people are not going to migrate from high-cost cities to rural areas, they are going to migrate from high-cost cities to slightly lower cost cities that still have an acceptable level of culture/amenities/jobs. Techies and other over-educated people are still going to spend almost all of their time interacting with people of a similar education and socio-economic status.

People left rural America for a reason, and a slight deviation from the coastal clustering is not going to change sufficiently to reverse the inevitable hollowing-out of rural counties.
