I don't see bitcoin as being a sign of 'modern'. It's for either an ideological belief in unregulated capitalism, or for money laundering. It's not a game I want to play, and I'm a working class guy on a pension anyway. The late great Douglas Adams summed up a lot of what is being said here:
“I've come up with a set of rules that describe our reactions to technologies:
1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
2. Anything that's invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
3. Anything invented after you're thirty-five is against the natural order of things.”
I'm excellent at wasting time, so I try to use my phone carefully. I never post here using my phone, for example. The only technologies I really dislike are those that track us. I see my US friends freaking out about government surveillance, but the private sector is just as dangerous. It's a matter of principle, as nothing I do is worth surveilling except by advertisers. But there were a lot of Ukrainians who probably said the same thing a few years ago, and suddenly, where they were became interesting to powerful people. You never know, and I'd rather play it close. Following the Douglas Adams formula, I'd be happy with no smart phone, however, the tech is enmeshed in everyday life. I can't even run my aquarium lights without one.
Self driving cars? Boring. I'd rather see an affordable rapid train system for convenient collective transport, and see every city with excellent public transport. Cars can be for the countryside, or for transporting larger things.
A lot of the tech features that are supposedly for me aren't. My new version of Windows is worse than a virus for its info collecting, allowing ads in and various corporate features. Plus they make me pay to have my privacy abused. I need it for my sideline work, but man, it is terrible. I'd like to see the destruction of the algorithm business model, but I won't see that.
