What tech scares you?

The accumulate effect of government tracking. I can't walk outside for 100 meters without being on camera. I can't buy a bus ticket without linking the purchase and ride to my identity. Etc.
- This is it for me also. I drive rural back roads to work and pass under thirteen cameras (that I know of) that are tracking license plates and other data. Add in phones, etc it's insane. Local police department is also asking people to register their home cameras with them too, so that they have all the cameras.
- Yes that's scary, democracy and laws only protect us to an extent. If the state changed we'd be in trouble.

Recommendation algorithms which are optimized to keep users hooked on a platform, rather than optimized for the best user experience, or truth, or happiness.
I think Alec Watson's video on this is excellent: Algorithms are breaking how we think (37:51)

Any gadget or device that connects to the internet. TVs, cell phones, gaming consoles, PCs, cars, ebikes, cameras (SO MANY CAMERAS), "smart speakers", home automation, etc.
Just because I am scared of them doesn't mean I don't use them, but I do refuse to connect them to the internet when possible, or else limit what data they are sending. It's exhausting though. I miss when the only devices that had internet connections were desktop computers.

Not tech per se but increase of always online services and ever more stringent security requirements.

AI. It's hard enough to work out what in the news is true. Now it's so easy to fake all sorts which has really scary impacts

Self-driving cars.
They're one hack away from being a mass murder machine that kills thousand to hundreds of thousands (depending on the size of the hack) all around a nation (or possibly even the world).
- I agree. A car can be a lethal weapon capable of mass destruction.

Mistaking LLMs for AI. Not because of the immature technology or the legally questionable procatices that made current levels possible, but the happy acception by the stupid and gullible, both in usage as in integration. I'm waiting for the first major catastrophe caused by outsourcing of a critical design to an LLM, being it a collapsing bridge, and exploding car, or an irresponsibly armed pseudo-AI controlled robot shooting people at random.
