I'm gonna predict biotech. Implanted chips that let you interact with LLMs directly with your brain. Chips that allow you to pay for stuff by waving your hand at a sensor. Fully hands-free videoconferencing on the go. As with blockchain and current LLMs, not something I fancy spending any time with, but people will call it the next step towards some kind of tech utopia.

You've been able to do that relatively cheaply for at least a decade. Nobody really does because the market for even minor surgeries that can essentially be replaced by having a pocket is pretty small.
Implanted neural interfaces have a lot of technical challenges that I think make them extremely unlikely as purely elective procedures in anything like the immediate future. AR glasses are way more plausible.
