Yes, but energy density doesn’t matter for most applications and the waste it produces is highly problematic.

Thats a chicken/egg peoblem. If enough renewables are build the storage follows. In a perfect world goverments would incentivice storage but in an imperfect one problems have to occure before somebody does something to solve them. Anyway, according to lazard renewables + storage are still cheaper than NPPs.

Slow, expensive, riddeled with corruption, long ago surpassed by renewables. Why should we use it?

Comparing users to MAU seems disingenuous. The fediverse has ~12 million users, according to fedidb and around 1.1 million active ones.

Most of them on Mastodon.
