Then there's cutesy web design; Flash ten years ago, "material design" now. Just because you can animate everything doesn't mean you should. (Annoyingly, the one browser thing that ought to be animated isn't. When you click on a link that exits the page, nothing happens until the new page loads, often leading to unnecessary double clicking. The browser should blank the old page, or grey it out, or dissolve to the new page, or do some kind of transition.)
As for the big stuff, the AI-driven future is going to be interesting. The big threat, as I point out occasionally, is not Terminator robots. It's Goldman Sachs run by a a machine learning system optimizing for maximum stockholder value.
