1. A book written by a machine makes a best seller list
2. AR goes mainstream towards the end of the decade. Google dominates the visual identification of things market.

4. Earth's temperature rises by 1.5C by 2030.
5. Widespread and inconsistent / incompatible regulation in multiple jurisdictions breaks the open web with many web based organisations choosing to restrict themselves to local markets rather than implement all of them.
6. PWAs become more popular than apps due to lower cost to build and higher revenues.

9. House prices will stagnate for the whole of the decade as boomers retire.
10. China will be the dominant world economy by the end of the decade (measured in GDP).
11. AI will significantly improve medical outcomes especially in early detection.
12. Renewable energy (including nuclear) will power most homes globally (50%+) due to regulations and cost efficiencies by the end of the decade (hopeful but it'll certainly trend in that direction).
13. Increasingly the wealthy will have a curated internet / app ecosystem that actively protects them from manipulation. The poor will have the opposite. This will increase populism and continue to contribute to the wealthy being confounded by it.
14. Developing software in a remote VM / container will become very popular (see Visual Studio Code Remote Extensions)
15. "serverless" i.e. building applications where the host machine is opaque will dominate software development, although this includes building serverless applications using containers.
16. Docker is no longer the most popular container runtime.
17. Regulation kills bitcoin.
