A personal note on this: 

I spent the last year of my blogging career focusing on exploring from first principles the fundamentals of blockchains. It hasn't gotten much attention, but I still believe it's by far the most impactful writing on my old blog.

Blockchains are only useful for strict global consensus, with the key overarching usecase being objective accounting.

For everything else, there are far more efficient and more decentralized options available/to be invented. Being dogmatic about only using blockchains has actively hindered growth for years - to expand the onchain economy we must adopt & invent better solutions, even if its not technically "onchain".
