Why are you baffeld? It's not that people are addicated to the technology, it's the technology changes. Is there are reason you aren't driving a 50-75 year old car today? Cars then, like today transport you at the same spped today as the did then.
The reason is the technology has changed. Cars today produce less polution, have more functionality and are safer.
Same is true with technoloy, (computers, cell phones etc.) Is there a reason you aren't uing records or casseete tapes to listen to podcasts or music today?
But here's the real reason you should be updating your technology.... Security. Your old technology can be used by cybercriminals to commit cyber crimes and you won't even know about it. There are cases where the onwer of odler technology has been arrested as being a cybercriminal becuase her device was being used in a cybercrime.
Because it's ridiculous to replace perfectly good equipment every few months to a year, shelling out money over and over for stuff I already paid for, turning resources into landfill at a rapid pace. Yes there is a reason I'm not driving a 50-75 year old car today, it's that I can't go out and buy one, and I can't just buy all the parts to maintain it. Also there were a few technological developments like fuel injection, disc brakes and crumple zones that really are a substantial improvement but those have been around for decades now. My daily driver is pushing up on 30 years old and I just hope I can find another one if something ever happens to it because it's so much cooler than anything new I've driven. If I could walk into a dealer and buy a brand new 80s-90s car today I absolutely would. You're absolutely right, cars today transport me just like cars did back then, and the fuel economy of my 1990 car is nearly as good as many similar modern cars. Since you mention safety, I'll say that this car is a replacement for a slightly older model that got rear ended by a semi truck at freeway speed and I walked away from that very violent accident without a scratch, you'd have a hard time convincing me that a new car is going to do appreciably safer than that and if I wanted to drive an unsafe car (or motorcycle) then that's my choice anyway. Sure a newer car has more "functionality" if you mean bloated gadgets, gimmicks and stuff to break or get outdated but you can have all that, I want to *drive* the car, I want to shift the gears, I want to feel the road, I don't need or want a bunch of bloat and distracting toys.
I do listen to music on vinyl quite regularly, yes I also have digital music that I can play from my smartphone or stream from various gadgets around the house, I'm not an old fart, I know how to use all that stuff and the convenience is nice but vinyl still sounds great and playing a record is a different experience, not to mention digging through dusty boxes of them in thrift stores looking for something good.
Now security with older devices, blah blah blah, there's a name for what you're saying, it's called FUD. Yes there have been a few notable security issues but find me an incident of older iPhones being taken over by cybercriminals (has it *ever* happened?) and I'll find you 10 times as many cases of modern, fully patched, up to date systems infected because of the one thing you can't patch, the user. I have spent many hours of my life cleaning up malware, crapware, viruses, and other garbage from countless computers and you know how many of those have been due to some exploit in old outdated software? Zero, none, so far it has *always* been a case of users installing sketchy stuff, falling for popups, email scams, bundled crapware, you name it. So save it, I'm not going to replace my devices just because of your unfounded worries about security and cries that the sky is falling. This security FUD is a very recent phenomenon, it started spreading fast right about the time software and hardware plateued and suddenly a 2 year old device wasn't hopelessly obsolete, tech companies started to panic as they scrambled to find new ways to keep selling more products. Having worked in various parts of that industry for years I've seen it from the inside, everyone is pushing towards everything as a service, subscription, perpetual income for the company and "OMG! Security! Hackers!" is one of the leading marketing cries to spin the benefits of software rental and half-assed, ship it now, fix it "later" tinker with it constantly development methodologies.
So yes, as somebody who buys something, takes good care of it and expects to keep it for 5, 10, maybe 20+ years and keep using it until it no longer meets my needs, I remain baffled how so many people think it's necessary to constantly replace everything, throw money away and burn through the world's resources.
