Vitalik has dropped another bomb in the space.
It's a new paper with Zoë Hitzig and E. Glen Weyl, which explores the problem space of funding for public goods and how to optimize it compared to fully market-based solutions.
Weyl is currently all the rage in parts of the crypto (and non-crypto) scene because of his Radical Markets book (where concepts like Quadratic voting and Harbinger taxes make appearances).
After the book got published, Vitalik started a relationship and collaboration with the author, and one of the outputs is this new paper.
Trying to summarize it in a few words, it's a new way to allocate funding for public goods, by understanding what the utility of the good is to end users, and stepping in with some public funding to make sure that those goods are funded appropriately.
If you are interested in the subject, there are a few choices. You could either read the paper itself, or you could opt for a great summary and analysis by Status
Coindesk also has a good article
with quotes from the authors.
The main thought that comes to mind here is, as highlighted in the past, the pace of innovation and how interdisciplinary it is.
If you're in the crypto space, you're either forced, encouraged or led to think about many, many different topics including technology in a broad sense, economics, monetary theory, policy, philosophy, politics and governance.
It's hard to find other spaces bubbling with so much new thinking, and I suspect that we will look back on this period as something truly special.
