I highly recommend you read this classic post from Patrick McKenzie: https://www.kalzumeus.com/2011/10/28/dont-call-yourself-a-pr...

You are not defined by your chosen software stack: I recently asked via Twitter what young engineers wanted to know about careers. Many asked how to know what programming language or stack to study. It doesn’t matter. There you go.

This is especially true now, since coding agents make it possible to work with any stack.

MCP is dead? 2 months ago

Exactly right. Co’s like Runlayer are growing like wild exactly for this reason. Without a central control plane MCP is a minefield.

It’s not enough to have unique ideas. You need capital, compute, people, distribution, customers… There’s huge appeal to joining a place that has all those things and lets you pursue your unique ideas without worrying about all that.

Was commenting on the quote in particular. It’s just a version of “the future is in your hands” which you can find in one form or another in many graduation speeches. Just seems odd to me to read a cliche line as something cynical.

Ali G’s version of it in his 2004 Harvard commencement speech:

“You lot will become powerful people who can change de future — and you need to, coz de world at de moment iz totally f—ed up.”

Come to think of it… very appropriate today!

AI tools make great team members even better

This is the predominant (public) talking point. And it’s true.

But along with that: when you have effective people becoming even more effective with AI, it becomes glaringly obvious who the INeffective people are. At which point it becomes hard to justify keeping those people around.

(That often includes people who are otherwise effective but aren’t utilizing agents and are therefore losing their edge.)

On the one hand, I get that it's a Sunday, and the CEO can't just write a mass email without approval from legal or other comms teams

This is not how things work. In a crisis like this there is a war room with all stakeholders present. Doesn’t matter if it’s Sunday or 3am or Christmas.

And for this company specifically, Guillermo is not one to defer to comms or legal.

Shaming like this doesn’t change people’s minds, it just makes them hide their feelings and introduces new or even greater feelings of guilt. The opposite of what you (hopefully) intended.

Exactly as happened with computer revolution... Expectations raised in line with productivity. In HN parlance, being a 10x engineer just becomes "being an engineer," and "100x engineer" is the new 10x engineer. And from what I can see in myself and others right now, being a 100x of anything, while exhilarating, is also mentally and physically taxing.

Love this announcement style. Direct, confident, and not a word longer than it needs to be. Gives major "the work speaks for itself" vibes. OpenAI's comms used to be like this, until it morphed into Apple-like grandiosity that instead comes off as try-hard.

Thoughts on Evals 8 months ago

Founder of a/b testing company accuses founder of evals company of misrepresenting how a/b tests are used in practice, then concludes by misrepresenting how evals are used in practice: "Or you can write 10,000,000 evals."

Could've easily been framed as "you need both evals and a/b testing," but instead they chose this route which comes across as defensive, disingenuous, and desperate.

BTW, if a competitor ever writes a whole post to refute something you barely alluded to without even mentioning their name... congratulations, you've won.

You don’t know how good they were really doing and you don’t know how good the offer was.

From what I know they were the most used inference provider by developers a few years ago, but since the Together AI and Fireworks only grew while Replicate seems to have stayed quiet. It’s a highly competitive low-margin business, so volume is critical and if you’re losing volume then you’re doomed.

The Augmentation vs Abdication framing is great. It also reflects my own experience in a different field: marketing. More specifically, coming up with messaging & positioning.

If you want something clear and compelling you can’t one-shot it, so you end up spending all day and night going back and forth with Gemini or Claude or whatever your cup of tea…

In the end I had something that looked great from the surface, but I felt completely lost in it. I couldn’t tell you what’s the core idea underpinning the whole thing, let alone explain it convincingly to the founders I work with.

The feeling is unsettling, but it has a benefit: it’s a signal that you’ve gone too far and need to re-calibrate.

In the end I found a great balance between the AI’s ability to synthesize vast information and offer endless alternatives to phrasing, with my personal taste and intuition. Augmentation.
