Depending where you are, then it's already happened.

Rural areas - a decade ago they were quoting A$18k per pole, and you'd need one pole per ~70-100 metres depending on terrain.

Of course, in rural environments you're more likely to want / need three-phase, and other high-draw appliances -- but conversely you've likely got access to much more roof or ground space to put panels, fewer restrictions on sizing and location for storage systems.
