I never used taxi services anyway; bus services are pretty good here, and I cycle.
A bigger issue is that a lot of services are "smartphone-only", and can't be done with a regular computer; sometimes this makes sense, sometimes less so. I partly get around this by running Android emulator on my computer when I really can't avoid it, which works "well enough". This will only get worse in the future.
I dislike telling people I don't have a smartphone; people look at you like you're some sort of freak. Recently someone told me that "I do not belong in modern society" shrug. I guess it's not inaccurate, as I dislike a lot of technology and feel it makes our lives worse in many ways (in spite of working as a programmer, but that's just for the money at this point; very hypocritical, yes).
Right now I have a "true" dumb phone (or at least, as dumb as you can get), which can just call and SMS and that's it. Oh, it also has snake, of course, and curiously it also has some other games you need to "buy" for €5 or so. IIRC the EU will switch off 2G in 2024 or so, so I guess I'll have to buy a slightly less "dumb phone" by then. We'll see.
