I've definitely turned into the paranoid nutcase within my friend group in recent years, I hate that everything is "smart" nowadays requiring an app/internet connection & account, just to do basic things that didn't require any of that before.
What's some things currently making you ramble like an old man?
Autonomous driving vehicles. I've worked in software for over a decade and if their internal processes are anything like the places I've worked then no thanks
It's worse. They use "machine learning". So nobody can know the failure modes before they happen.
We still don't have a reliable enough way to automate trains, and that's a (mostly) centrally controlled and closed system. The driving assists like automatic braking can at least be tested to a reasonable confidence, but I'd rather drive drunk than sit in a fully autonomous vehicle.
I work in IT and you can basically track enthusiasm about self driving cars along the lines of technical knowledge
