@nickchapsas Had personal annual subscription. Still 9 months to go. So I think twice when writing prompts with context, to make the agents work as long as possible.

VCs, please stop funding this slop. We’re entering clown world with the amount of AI building we’re seeing. 🤡🌎

All I see in the data infra space is companies building infrastructure for AI Agents with the obligatory buzzwords like A2A or MCP.

Who is productionizing these AI Agents?

Two years of marketing hype in, I have literally only seen ONE talk about an AI "Agent" in prod. It's by Uber and it's used for code generation. First off - it's a dev tool and second - it's not even an agent, it's a workflow.

Who honestly thinks the future of software architecture will be hundreds of AI Agents talking to each other, similar to microservices today?

Does anyone ACTUALLY believe this is what the world will be in 5 years?

Can they comment here and share their perspective?

The data is pointing to the opposite.

• We haven't seen any major LLM advancements since GPT-4.
• All frontier model companies are grossly unprofitable with no sustainable path.
• A lot of investments between big tech are circular (recycling revenue)

Even in a winner-take-all model, OpenAI is burning $5 BILLION a year.

Anthropic, the number two, is looking way, way worse regarding its revenue model.

What happens when the funding stops?

Companies chasing investor interest via shiny narratives are missing the forest for the trees - we, the engineers, need practical solutions.

That's what's going to last.

Fortunately, I see two trends growing quietly behind the spotlight (the sloplight?) of AI.

They will most certainly survive a dot-com like crash if that were to happen.

They are:
• Small Data
• The “Just Use Postgres” Renaissance

The common theme between both?

Simplification.

♦️ Small data is the cure for the Big Data hangover that tech collectively went through in the 2010s. It’s the group realization that:

• organizations don’t use that much data
• hardware is getting really, really good

Most applications will never see a terabyte of data, even if they’re successful.

Snowflake and Redshift-published data showed that 99.9% of real-world queries fit on one node. 💡

And the nodes are becoming super beefy. AMD released a 192-core (!) CPU this summer. 2025-era SSDs can do 5.5 million random reads a second and 28 GiB/s sequential reads.

Embedded and simple systems like DuckDB are going viral for a reason.

♦️ Postgres is doing to data infrastructure what the monolith comeback is doing to the microservices architecture.

It’s the group realization that Postgres can handle 80% of companies' needs. And it does it with 20% the effort.

It’s not the extreme view where "when you have a hammer, everything looks like a nail".

👉 It’s the extremely reasonable and practical application of reducing the amount of system sprawl in your organization when that sprawl isn’t warranted.

Instead of MongoDB, Redis, an AI Vector database, Snowflake and Elasticsearch - you can use tsvector, pg_mooncake, pgvector, unlogged tables and jsonb in Postgres.

Life becomes significantly simpler when you don't have to manage 5 different systems. There is a ton of organizational overhead in having to:
• learn their nuances/configs/gotchas,
• learn their UIs and terminology
• learn how to deploy and upgrade them safely
• build operational expertise
• write runbooks for them
• debug them
• test them
• find, hire and retain talent that understand them
• keep up with their ecosystems
• etc.

Paying this organizational overhead for zero significant gain is not worth it.

It's all common sense.

@SrEdm00 @pierceboggan @code #2 (see the posted picture in the parent tweet.) and then you should have that agent available in the copilot chat. (here I found out some docs:. https://t.co/h9COdw7Uwl). It works nicely.

[Zemacik @Zemacik]

@SrEdm00 @pierceboggan @code #1 I installed VS Code insiders preview, then in my project folder under .github/agents/.. created a few agents with names like 'https://t.co/BCNV296HcF','https://t.co/VlHbjSuLRl', assigned tools in frontmatter like 'tools: ['runTasks', 'edit', 'search', 'todos', 'runSubagent']'.

Wild how AI killed the 'new JavaScript framework every week' era.

I really appreciate this point:

"One great thing about web components is that they enable non-JavaScript developers to create richer and more interactive experiences using HTML."

JavaScript-focused developers often forget that there is a MASSIVE population of web creators who author entirely or nearly so in only HTML and CSS. Not everyone is experienced or comfortable with JS and there are many scenarios where creators cannot bring in the tooling or setup that is required for a JavaScript framework. However, they can add a script tag that adds new HTML elements that they can use like any normal HTML throughout their site.

We have to remember: the Web is for everyone, not just JavaScript experts. Writers, marketing directors, artists, lawyers, activists, teachers, makers, and on and on. This is fundamental to the democratic nature of the web. To solely focus on JS developers is to create a class system, where only the privileged experts have access to the Web's full potential.

That is not acceptable.

The merchants of complexity will try to convince you that you can't do anything yourself these days. You can't do auth, you can't do scale, you can't run a database, you can't connect a computer to the internet. You're a helpless peon who should just buy their wares. No. Reject.

Open Letter to Marc Andreessen (@pmarca)

I was saddened but unsurprised to observe that your recent Techno-Optimist Manifesto received more than its share of negative coverage in America and Europe.

Your armchair critics in the press highlighted how they’d read your 5,000-word manifesto “so [we] don’t have to”, and, smug in their luxury beliefs, lambasted your audacity in defending or—God forbid—promoting capitalism and free markets, the very foundations they owe their comfortable lives to.

You had surely hoped for a better class of critics, but as a self-made man in this twilight of Western civilization where could you have aspired to find them? It could not have been in the tech press, which now bears little resemblance to, say, Wired as we knew it back in the ‘90s.

No, these were the kind of journos who painted the night sky “dystopian” after Starlink redefined connectivity, and who maligned the test launches of Starship—the most powerful rocket ever built—as “failures”. Nearer to me, over here in Dubai, they called the Burj Khalifa—the tallest skyscraper on the planet, reaching over half a mile into the sky—“a frightening, purposeless monument”.
