Please be "ai"... Please be "ai"...
I'm going to be bold. The internal combustion engine car.
There will be a tipping point where nobody wants to maintain the highly intricate manufacturing for them, and they will stop very quickly. Electric motors are the future and the transition is accelerating. We're currently around 20% of new sales and I expect after 60-70% ICEs will just disappear from sale.
If anything I think DVDs and Blu-rays are going to rise. All across the media landscape people seem to be getting annoyed with the "own nothing" society we're in. The thrift stores are full of thousands of DVDs for barely any cost. Last week I bought the Matrix 2 and 3 and Der Untergang in DVD for like 3 bucks. Way easier than figuring out in which streaming service to watch them and what OS and browser will let it play at HD resolution. Once "the youth" picks up on this like they did with CDs and digicams the DVD will be back.
Recently In bought a Blu-ray of Star Wars Andor because I love the series and want to support it, but Disney+ wouldn't play beyond 480p on my setup. My trusty old PS3 plays it like a dream and the resulting image is ridiculously sharp compared to streaming.
CDs, cassettes, and vinyl are already booming or in the rise again. And the streaming audio landscape is arguably way nicer than the streaming video lanschape. In photography there's also a wave of film and early digital camera hype.
I hope that the next 10 years brings the resurgence of the physical medium and ownership. And if not that, the resurgence of the high seas.
Windows for home consumers/home PCs hopefully.
I feel like DVDs/Blurays already disappeared 10 years ago and are now making a comeback. Same for CDs. Streaming services don't let you own anything, and if they pull something down, you're SOL. Self hosting Plex and ripping my own disks has given me a level of freedom not possible with netflix et. al. Especially since DVDs are considered garbage to most people now, you can set up your own streaming service for you and your friends and family for cheap. No piracy necessary.
I don't know about DVDs, nearly 2 decades ago I thought optical media was dead and yet somehow it's still here.
3G networks
I don't think we will be losing optical disks ever.
If burned properly they hold storage for a very long time without data loss. IIRC Facebook burns optical disks for old photographs and instead of having a hard drive array or tape library they had a RAID based optical disk system.
Optical disks are great, but not for the daily user since most media content is online and most storage is judged on being rewritable.
Tablets.
The market for them is very thin. With phones getting bigger and convertible laptops being more lightweight I don't see much market for tablets.
Which is a shame because it's s good format for comic reading and more durable than a convertible laptop (they always break by the hinges) but I think in ten years it will be quite hard to find a tablet for sale.
Commercial TV
Social media as we know.
Aux cables
Car keys/fobs
my answer varies quite a bit depending on whether we mean tech that will be relegated to specific niche use cases and markets, tech that will no longer be produced at all, or tech that can't be found any more, even used.
the first category could include a lot of things, like most of the other suggestions that have already been suggested here, but i don't think there's any chance of blu-ray discs or desktop computers being totally gone in that time frame. the second category will probably include small gasoline powered cars, at least in some countries. and the third category will probably include most standard incandescent or CFL light bulbs, but they might still exist in some niche applications.
Bike locks. Surveillance will be expanded to the point that petty crimes will become impossible.
Why the downvotes? Do you disagree with the expectation or do you dislike the development? The question is about what will happen, not what we want to happen. I don't like it but I expect full surveillance in 10 years.
