Platform Decay, Decentralized Marketplaces, and Urbit

[Ad-supported web dominates because banks failed to make micropayments and other 'real money' infrastructure accessible.]

[Ad sales incentivize the 'sharing' or 'renting' economy because people are less likely to return after buying to own.]

[When search results make it difficult to buy a hammer, it causes the culture of 'building things' to suffer.]

[The test of any tool is its ability to shape the world.]

[Calm commerce follows naturally from calm computing.]
