I seriously doubt many of your predictions.
2. Valorizing excess
Not sure what exactly you mean by this, but having more than you need and showing off is basic human behavior, and I don't see a reason that will change.
3. Bonfires and fireworks
Bonfires are fun and so are fireworks. They have some downsides, but not more than many other fun things we allow.
4. Anonymity
There will always be places where you can act anonymously or pseudo anonymously. See 4chan and bitcoin for example.
5. Air, noise, and light pollution
There will always be the next kind of not-yet-illegal pollution, and the person to profit from inflicting it upon the rest of us.
6. Having more than 2 kids
Most people will have 1-3 kids, some will have more. Nothing absurd about reproducing.
8. Buying new stuff all the time
See 1
12. Golf
Might be less popular, but why absurd?
13. Body modification and tattoos
Basic human desire to control your body and what you look like. If anything it will be more popular as technology improves.
15. Running unaudited code
With the halting problem on one hand (making automatic auditing impossible) and the high value of software on the other, I don't see any way around this anytime soon. Maybe some AI based solution.
16. Non-tailored medicine
One prediction I fully agree with! Especially many invasive examinations we consider standard today.
17. Tribal politics
Human nature...
20. Burial
Also human nature. Not the American style burial with the huge casket and embalming and whatnot. But some kind of burial will always be the norm.
21. Men standing to pee
???
23. Tipping
24. Advertizing
Human nature...
31. Automotive fatalities
Maybe on the road. But what about space fatalities?
