A bunch of random predictions that I typed as they came to mind:
1. Google has a serious competitor in the search engine space, but it is from an already established corporation and not a new startup
2. An internet celebrity (i.e. fully-online career like a YouTuber) is elected leader of a major country
3. Windows drops 32-bit support
4. There still hasn't been a huge, crippling state-sponsored cyberattack. The rhetoric will remain as it is in 2020
5. Fake news is no more or less relevant/damaging than it is in 2020, but it will still be in the public consciousness
6. Similarly, deepfakes will be politically weaponized, but only a few people will fall for them, as they will be debunked the same way that fake news stories were debunked in the 2010s
7. Partly with the help of social media, several western countries will elect governments that explicitly identify as fascist or communist
8. As the developing world becomes more connected to the internet, userbases of popular websites will become more tilted toward countries like India and China
9. China will abandon its Great Firewall
10. The major players in the tech industry will not change. Google, Apple, Microsoft, et al. will still dominate, even as they attain increasingly negative press coverage and customer dissatisfaction. Silicon Valley will not be meaningfully disrupted until the 2030s
11. Internet privacy will become more politicized and more people will care about it as a result (i.e., as it ties into other beliefs and identities)
12. Internet-based cults will become prominent, possibly some as large as Scientology was in its heyday
