The trend towards earlier break-up (both BUS and BUE) in all areas is stronger than any previously identified and in some study areas exceeds one day per year.

world after capital

https://worldaftercapital.gitbook.io/worldaftercapital/readme

non-linearities

non-linear advancement expand dramatically the space of possible where extrapolation predictions are useless.

invention	scarcity shift	age
agriculture	food to land	agrarian
industrialization	land to capital	industrial
digital technology	capital to attention	knowledge

individual freedoms

smooth this transition expanding individual freedoms:

1. Economic, unlock time
2. Informational, unlock knowledge
3. psychological, unlock rationality

values

the knowledge loop (learn, create, share) will reduce attention scarcity and to benefit humans and other species need a set of values:

1. critical inquiry
2. democracy
3. responsibility

Digital Technology

zero marginal cost and universality of computation combination is unlike anything we have had before.

intelligent machines and knowledge accessible to all of humanity
