Even better, _ALL USEFUL_ AI retrival systems are insecure by design, because all those RAG vectors that sells vector-databases? That's basically your documents lossily encoded.

>That's basically your documents lossily encoded.

Vector embeddings are lossy encodings of documents roughly in the same way a SHA256 hash is a lossy encoding. It's virtually impossible to reverse the embedding vector to recover the original document.

Note: when vectors are combined with other components for search and retrieval, it's trivial to end up with a horribly insecure system, but just vector embeddings are useful by themselves and you said "all useful AI retrieval systems are insecure by design", so I felt it necessary to disagree with that part.

if you feel cheated now, I promise you'll feel more cheated if they did this after you rely on it for several months. the least worst option is to change pricing as early as possible.

The real tragedy isn't IRC clients, but that IRC missed its chance to become the dominant decentralized protocol before Slack/Teams took over. The core issue wasn't just tooling. IRC's protocol fundamentally lacked what modern teams need: native multimedia support, seamless file sharing, persistent searchable history, and rich formatting. While IRCv3 improved extensibility, it didn't address these feature gaps. It seems that IRC's simplicity was both its strength and fatal weakness. Great for tech communities, but too bare-bones for mainstream adoption. I feel that we traded decentralization for features, and now we're stuck with proprietary silos

this is just XMPP and it has been around for years before Slack was even a thing

Slack won anyway for the same reasons most centralised, commercial, closed sourced products often win: less fragmentation, more marketing, stronger network effects, simpler onboarding for normies, richer integrations, and most importantly, an enterprise sales team that actually showers

clicked hoping for an out of distribution argument for why a specific type of Japanese martial arts is perfect for git users :(

Excuse me, it took the auther 30-40 seconds (0m33.260s) to build the Linux kernel on an M2 with 32GB RAM? Surely that's a typo?

1. modern computers are insanely fast

2. they compiled a version of the kernel with as many configurable options disabled as possible

3. modern computers are insanely fast

>>> So the three reasons readers might not already know what you tell them are (a) that it's not important, (b) that they're obtuse, or (c) that they're inexperienced.

(d) because it's false.

I'm not saying PG's essay is false, but my scientific upbringing, and rare moments of humility, compel me to include this option.

1. PG is implicitly talking about good essays. And it's very hard to write a good essay if you don't believe it's true.

2. Whether something is true has nothing to do with whether the reader knows it. I know many false things and ideas.
