Lithium ion batteries will be looked at as primitive and dangerous technology within our lifetimes. That we sought to construct buildings full of them in the name of environmentalism will go down in history as one of the most gruesome acts of hubris.

(This is not a post against intelligently built and decentralized home battery systems, resilient device batteries, or even car battery systems for that matter- though they will all get upgraded from lithium ion in due time and so the statement stands)
