I mean, regardless of 'obsolescence', what the author of the article fails to understand is that there will always be niches for pretty much all of these products, and niche isn't even quite the right word. Enthusiasts and hobbyists will pretty much always be using most of this technology. The only thing they got right is *maybe* incandescent lightbulbs, I do see those going away simply because they're inefficient. The rest of it? Nonsense.
Wired headphones are going away? Bullshit. There's still a pretty big 'audiophile' community who are buying high-end wired headphones, DACs, amplifiers, etc. As cringy as that community can sometimes be, they are absolutely correct when they say high-end wired headphones can deliver sound quality that wireless headphones simply can't. I'm not referring to Beats by Dre either, those are trash. Plus, battery life is a concern, and just because Apple wants to remove functionality so they can sell you more proprietary peripherals, doesn't mean others are doing the same.
Remote controls aren't going anywhere either. Contrary to popular opinion, not everyone wants to pay for a wiretap, voice controls still regularly get things wrong, and not everyone wants to rely on 'the cloud', voice commands or phone apps to do something as simple as adjusting a thermostat, turning on the TV or turning on their lamp. Infact, 'smarthome' concepts are still mostly a gimmick at this point.
Gaming consoles aren't going anywhere either. They've still got a big market share so why on Earth would they stop producing them?
Digital cameras are developing, not going away. Many of them still offer more settings and better picture quality than smartphones. Hell, analog cameras are still around and making somewhat of a resurgence among hobbyists and enthusiasts.
Conventional, physical locks are CERTAINLY not going anywhere. Electronic locks and similar suffer from the same problem as most smarthome accessories. If the power goes out, and it eventually will, you're pretty much fucked. You won't be able to get into your god damned house unless you have a generator/backup battery or power supply, and while that's feasible, most people aren't going to spend that much money and time to configure it.
Incandescent lightbulbs, I'll give you that one, they are probably on their way out and have been for a number of years. Still, there are people using them simply because they haven't gone out and while their market share has dwindled, they're still on store shelves for people to purchase.
2G, I'll give them that one as well, it's on it's way out. However, a lot of physical tech still uses 2G and 3G signals to communicate. A lot of monitoring hardware for pump stations, water meters, substations, oil and gas wells, etc. use 2G and 3G to communicate information that they monitor. They'll eventually have to upgrade but as we know from all of the businesses still running XP on enterprise hardware, it likely won't happen quickly.
Even though cloud storage is getting better, a physical back-up is still a great thing to have. When you're preserving data, you want several layers of redundancy. External storage isn't going anywhere, it'll just improve.
Physical media is on the downturn, but many people still prefer to have a physical copy of something rather than paying for a digital copy that could disappear some day. Additionally, you'll always have collectors. Cloud-computing and cloud storage and digital downloads are fine and interesting in their own right, but the fundamental problem is, you're going to be putting someone else or some other entity in control of your data, your purchases and with cloud computing, even your hardware. Most people, myself included, don't like that at all. It's useful and convenient, sure, but services can go down, get breached or get discontinued. Then what? You're fucked. If, on the other hand, you lose your physical media/storage or damage it in some way, that's incumbent on you and nobody else. They still have not sufficiently addressed privacy, vulnerability and reliability problems in terms of cloud-storage [which still utilizes physical storage/media anyway at some point] enough to make it a viable replacement for currently existing tech.
Cable TV is going to be around for a long time yet, and it'll keep getting worse. Still, for a lot of older people, it's the only thing they know and streaming services still have a lot of issues before they become fully viable. To put it simply, people don't want to pay for ten different streaming services/subscriptions because of corporate/intellectual property fuckery. Without a doubt, cable will have to adapt and improve some, but it'll still stick around.
I think the author of this article just hasn't paid much attention to what things are like in the trenches. Most of the 'brave new world' type technologies that are developing are still deep in the stage of being gimmicks. The old standbys aren't going anywhere quite yet. They also act like all of this tech will just disappear one day and be replaced instantly. The military still uses floppy disks.
