Continuing to carve out economies of scale in battery + photovoltaic for another ten doublings has plenty of positive externalities.

The problem is that in the meantime, they're going to nuke our existing powergrid, created in the 1920's to 1950's to serve our population as it was in the 1970's, and for the most part not expanded since. All of the delta is in price-mediated "demand reduction" of existing users.

A lot of the biggest data centers being built are also building behind the meter generation dedicated to them.
