2. A Microsoft first-party Android device is launched, following a similar attack strategy they are currently starting with Edge on Chromium: fork, improve, destroy.
3. ARM takes over... actually, a more bold prediction: x86-64 remains king, and ARM is not able to conquer beyond the mobile market, despite present-day feelers.

6. Disney Plus struggles with choosing consolidating the Disney "family friendly" brand and the sort of Game of Thrones gore-fest content demanded by millions of subscribers, leading to either a rebranding or an off-shoot for "adults" a la "Adult Swim" or "Nick at Night".
7. At least one of the big streaming services (Cockatoo or whatever NBC has?) throws in the towel and merges with another.
8. Hong Kong remains in turmoil for all of the 2020s.

10. Working remotely is still a pipe-dream heralded by a lucky subset of HN posters.
11. A battery breakthrough revolutionizes mobile devices and elevates electric cars to make combustion engines even more obsolete.
