The Ministry for the Future makes open source social media look easy.

I did like the book but I also thought they solved huge problems in a single short chapter with minimal detail.

In one chapter it's mentioned that one of the characters is working on some open source social media. A few chapters later it becomes the dominant social media in the world... oh and also payment method... Oh and blockchain...

Being a big fan of Lemmy, I think the book is a bit optimistic.
