Old iPhones Are “Incredibly Dangerous,” Says Appliance-Obsessed Comedian — 5ch: “Your Router Would Get Hacked First”

The story

Kajigaya Takuya, known as a “home-appliance comedian,” pointed out on Chihara Junior’s YouTube show that it’s “dangerous” for fellow comedian Zabungle Kato to keep using his iPhone 8. His reasoning: the rise of AI has made it much easier to hijack devices. When the story was reposted to 5ch’s Geino/Sports News+ board, comments piled up arguing that routers and how people handle their personal data are bigger problems than device hijacking, and that simply replacing the battery is enough to keep an old phone going without worry. The thread ended up split between people who felt the danger itself was never spelled out concretely, and those defending Kato, saying he has a point.

Kajigaya Takuya, the talent known as a “home-appliance comedian,” appeared on the official YouTube channel “Chihara Junior YouTube,” updated on the night of the 28th. He shared his view that continuing to use an old version of iPhone is “dangerous.”

This episode featured a barbecue hosted around comedian Chihara Junior. Comedian Zabungle Kato, invited to the get-together, was asked point-blank in the flow of conversation what he thought about the iPhone 8 he’d been using for years — “What do you think?”

Kato said, “I love the iPhone, but honestly it does everything I need — it’s plenty (functionally),” and “I’m not really having any problems.” Hearing this, Kajigaya commented, “Just going by first impressions, that’s dangerous.”

Watching Showa-era retro exploration videos on YouTube beats watching the Piece-kun mascot at Omiya Park any day.

Even if it's not quite "Mythos-tier" AI, once a sufficiently advanced AI is in play, the latest iOS isn't really much safer either.
6AnonymousSep 29, 2026 22:38
80% of 5ch users ("nearer") are on Android anyway, so this isn't our problem.
7AnonymousSep 29, 2026 22:39
At this point it's basically the same as walking around with your balls hanging out (´・ω・`)
8AnonymousSep 29, 2026 22:39
Wait, huh? Didn't Rahmens say in that commercial that Apple computers don't get viruses??? (referencing Rahmens' old Japanese "Get a Mac" ads)
10AnonymousSep 29, 2026 22:41
Can this guy even code? Does he even know what a security hole is?
12AnonymousSep 29, 2026 22:42
Wouldn't a flip phone (garakei) be too old for anyone to even bother hacking?
14AnonymousSep 29, 2026 22:43
Getting hacked, then
saying "man, that sucks"
— that's the whole package.
15AnonymousSep 29, 2026 22:44
It's not about having nothing embarrassing to hide — the real danger is your phone getting used as a launchpad for crime
and you getting treated like the criminal.
Kato doesn't get it at all.
17AnonymousSep 29, 2026 22:45
This isn't just about him, you know.
Everyone connected to him is also at risk of getting hacked.
18AnonymousSep 29, 2026 22:46
Didn't the iPhone 5s get an update recently?
19AnonymousSep 29, 2026 22:49
I still use the very first iPhone 5 I ever bought as a music player — is that bad?
47AnonymousSep 29, 2026 23:15
Re: #19
I use the yellow 5c I bought back in high school as a stand-in for an iPod touch too.
My bathroom speaker dock is old too, only fits phones up to about the size of a 6, so I use it strictly for listening to Apple Music and watching YouTube in the bath.
Got the battery swapped two years ago too, so it's still going strong.

It's like arguing over whether a creepy otaku in a Kevlar hoodie or one in a cotton hoodie
would come out of an Ecuadorian slum unscathed.
23AnonymousSep 29, 2026 22:51
Ha, you idiots — Apple's been siphoning off your data this whole time anyway lol
24AnonymousSep 29, 2026 22:52
I use a secondhand Sense4 Plus.
AQUOS phones are kind to an old man's wallet.
25AnonymousSep 29, 2026 22:52
"Whaaat?!"

— the type who rushes out to switch phones over that kind of reaction is probably the type who falls for scams.
26AnonymousSep 29, 2026 22:54
If AI is really that amazing,
then no matter how far iOS advances, a future's coming where its security gets cracked instantly.
29AnonymousSep 29, 2026 22:57
I use my SE2 purely as a music player, zero problems…
30AnonymousSep 29, 2026 22:58
Sure, some apps stop working on older models,
but if you're just making calls and browsing the web a little, you probably don't want to switch.
31AnonymousSep 29, 2026 22:58
Your router would get compromised first anyway, so it's a non-issue.
33AnonymousSep 29, 2026 22:59
A battery replacement alone only runs a few thousand yen anyway.
34AnonymousSep 29, 2026 22:59
Getting hacked is honestly pretty hard to pull off lol
If anything, you should worry more about falling for scare-tactic ads lol
35AnonymousSep 29, 2026 23:00
Why does everyone just default to talking about iPhones? Bring up Android ("doro") too.
36AnonymousSep 29, 2026 23:01
I only use it for calls, so I'm totally fine.
37AnonymousSep 29, 2026 23:02
For Android it's 8.0 (API Level 26) or later, yo.
For "iPon" (iPhone), pretty much anything from the 5s onward is basically fine, yo.
38AnonymousSep 29, 2026 23:02
Apparently cutting-edge executives don't even use iPhones anymore.
39AnonymousSep 29, 2026 23:04
I upgraded from the 12 to the 17, and battery life is more than 3x better, charging speed more than double.
An 8 must be super inconvenient by comparison.
40AnonymousSep 29, 2026 23:04
Rather than worrying about your garbage personal data, shouldn't people be more worried about getting impersonated?
44AnonymousSep 29, 2026 23:11
I've got the 16e but I'm still on OS 18.
Is everyone else already on 26 or 27?
45AnonymousSep 29, 2026 23:13
Honestly, Kato's probably right here.
The fact that he's still using an 8 in the first place means "dangerous" doesn't even enter into it.
He's clearly just using it as a plain phone, not really as a smartphone.
The whole premise of "he's got all sorts of personal info loaded on there" is wrong to begin with.
46AnonymousSep 29, 2026 23:13
Main phone's an Xperia 1, backup's an SE2.
49AnonymousSep 29, 2026 23:17
I'm into cameras, so I went and tried out the latest iPhone's bokeh feature.
Came away thinking "huh?" — hard to tell the difference. A big standalone camera is still stronger.
54AnonymousSep 29, 2026 23:21
AI isn't actually that all-powerful, though.
68AnonymousSep 29, 2026 23:33
Re: #54
Right now it's an AI that's busy rummaging through secondhand bookstores,
so it probably hasn't gotten around to iPhones yet, has it?

Background and Key Points of This Debate

iPhone security doesn’t really degrade because of the hardware’s age itself — it drops off sharply once the device stops receiving OS updates. The iPhone 8 only supports up to iOS 16, and has gone without subsequent vulnerability patches ever since. Kajigaya Takuya’s comment appears to have this “end of support” issue in mind, but on the thread, the phrase “AI could hijack it” came across as vague, giving the impression that alarm spread on its own without any technical backing. Reactions split depending on whether people treated the hijacking risk as genuine harm, or saw “more realistic entry points” — like router vulnerabilities or being lured to scam sites — as the bigger threat, with the latter view being more dominant on 5ch. Another point of disagreement was that with an older model like the iPhone 8, if it’s used for a limited purpose such as calls only or music only, actual exposure of personal information is minimal — meaning people’s baseline assumptions about the level of risk differed from person to person.
