Man, you gotta hear about some of the stuff popping up on Hacker News today, Tuesday, December 9, 2025. It's been a wild mix, mostly AI stuff, but some other cool bits too.

AI Dreaming Up the Future

First off, this one dude did a "Show HN" where he used Gemini Pro 3 to hallucinate what the HN front page would look like ten years from now. Seriously, check it out: HN 2035 Front Page. The comments were pretty funny, like how some of the AI's jokes about the future sound a lot like old sci-fi writers like Philip K Dick. Someone even linked the prompt they used, which was pretty simple. And ironically, one guy posted about his text editor that *doesn't* use AI, saying he'd repost it in 10 years!

To AI or Not to AI?

That led right into another big discussion: should replies like "I asked $AI, and it said..." be banned on HN? The thread was buzzing, with folks on both sides. Some people are like, "nah, it's just a disclosure," but others are super annoyed, saying they'd just ask the AI themselves if they wanted its opinion. One commenter mentioned an AI giving a "shocking but correct" answer about misinformation, which is kinda wild.

Happy 10th, Let's Encrypt!

Switching gears a bit, Let's Encrypt is ten years old! Can you believe it? They posted about their anniversary. It's crazy to think how much easier they made getting SSL certificates for everyone. People in the comments were reminiscing about the old days, like how much time they wasted with OpenSSL commands or dealing with sketchy certificate authorities before Let's Encrypt came along. Definitely a game-changer.

Mistral's Latest AI Toys

Then Mistral, you know, the AI company, released some new stuff: Devstral2 and a Vibe CLI tool. Their announcement was on their site. The comments got into this whole debate about what "open source" even means these days, with some people arguing that big tech companies are kinda twisting the definition. Someone else made a good point about how AI models are fundamentally different from hiring a human worker, with all their "subliminal learning" and weird quirks.

The Sudden Jump of AI

There was a cool article called "Horses: AI progress is steady. Human equivalence is sudden." It talks about how AI might seem to inch along, but then suddenly hit a big breakthrough. The comments were gold. A lot of people were complaining about how terrible Google search results have gotten, with all the sponsored links and SEO spam. Someone else was pretty skeptical, asking where all the flying cars and humanoid robots we were promised are, basically saying people cherry-pick AI successes.

Coolest 3D Website?

Speaking of cool, someone posted about "Handsdown one of the coolest 3D websites" – it's bruno-simon.com. If you haven't seen it, it's like a little interactive 3D world. People were really impressed, wishing that kind of web development was more accessible to everyone. One person even said playing good video games might be better for your brain than just scrolling on your phone, which I totally agree with.

PeerTube Gets a Nod

And finally, something a bit different: PeerTube, that decentralized video platform, got recognized as a "digital public good" by some alliance. You can read about it here. One comment mentioned that being a "digital public good" actually helps projects get chosen for UN and government contracts, which is pretty neat. There was also some discussion about the "fatal flaw" of ActivityPub systems, where your online identity is tied to a specific server, which can be a hassle if that server goes down.

Alright, that's the gist of it, man. Talk soon!
