“in the next week, I’ll do a whole month’s work. and no one will know.”
incredible piece.
every senior *anything* should read this. PMs, designers, consultants, finance VPs (et al) are not immune to this spiral. you can prevent it happening to you if you can recognize it first.
new post: the senior engineer death spiral
sunilpai.dev/posts/the-senio…
a friend just started a big job and asked for some advice. so I braindumped a monologue about a super common failure mode I see with engineers and posted it here, hope it helps whoever it can.

I was chatting with my buddy at Google, who's been a tech director there for about 20 years, about their AI adoption. Craziest convo I've had all year.
The TL;DR is that Google engineering appears to have the same AI adoption footprint as John Deere, the tractor company. Most of the industry has the same internal adoption curve: 20% agentic power users, 20% outright refusers, 60% still using Cursor or equivalent chat tool. It turns out Google has this curve too.
But why is Google so... average? How is it that a handful of companies are taking off like a spaceship, and the rest, including Google, are mired in inaction?
My buddy's observation was key here: There has been an industry-wide hiring freeze for 18+ months, during which time nobody has been moving jobs. So there are no clued-in people coming in from the outside to tell Google how far behind they are, how utterly mediocre they have become as an eng org.
He says the problem is that they can't use Claude Code because it's the enemy, and Gemini has never been good enough to capture people's workflows like Claude has, so basically agentic coding just never really took off inside Google. They're all just plodding along, completely oblivious to what's happening out there right now.
Not only is Google not able to do anything about it, they don't seem to be aware of the problem at all. I'm having major flashbacks to fifty years ago as a kid at the La Brea Tar Pits, asking, "why can't they just climb out?"
My Google friend and I had this conversation over a month ago. I didn't share it because I wanted to look around a bit, and see if it's really as bad as all that. I've been talking to people from dozens of companies since then. And yeah. It's as bad as all that.
Google is about average. Some companies at the bottom have near-zero AI adoption and can't even get budget for AI. They may have moats and high walls, but the horde is coming for them all the same.
And then there are a few companies I've met recently who are *amazingly* leaned in to AI adoption. One category-leader company just cancelled IntelliJ for a thousand engineers. That's an incredibly bold move, one of many they're making towards agentic adoption. In my opinion, that company is setting themselves up for a _huge_ W.
As for the rest, well, it's the Great Siloing. Everyone's flying blind. With nobody moving companies, no company knows where they stand on the AI adoption curve. Nobody knows how they're doing compared to everyone else.
Half of them just check a box: "We enabled {Copilot/Cursor} for everyone!" Cue smug celebrations. They think this is like getting SOC2 compliance, just a thing they turn on and now it's "solved." And they don't realize that they've done effectively nothing at all.
All because of a hiring freeze.

OK, well. I ran /autoresearch on the the liquid codebase.
53% faster combined parse+render time, 61% fewer object allocations.
This is probably somewhat overfit, but there are absolutely amazing ideas in this.

It’s Next.js Liberation Day.
The #1 request we kept hearing: help us run Next fast and secure, without the lock-in and the costs.
So we did it. We kept the amazing DX of @nextjs, without the bespoke tooling, built on @vite. We’re working with other providers to make deployment a first-class experience everywhere.
Next.js belongs to everyone.

Tailwind's lost 40% of their web traffic, a bunch of revenue, and yet has 300%+ growth in npm installs and usage at all time highs.
An incredibly raw, honest take from one of our industry's best on the realities of running a business in the midst of the creative destruction AI is bringing.
Worth a listen, the whole way through.
while my friends played starcraft, i studied the compiler. and now you come to me ...
wait hold on your saying niche computer knowledge is commoditized now and what matters is coordinating a bunch of agents with lots of quick task switching and high APM

What defines a correct program? What makes a good programmer? The answer depends on what culture of programming you subscribe to!
This has been a long time in the making, but my open access book on the history of programming is available for pre-order!

I was right there in 1971. The whole area was rubble of Palestinian houses that had been demolished after the families living in them were thrown out so Jews could have more room to pray at the Wall.
I didn't really know what I was seeing. Now I understand clearly.
There is no "holiness" in a house built on stolen land.

Been building a @rescriptlang MCP server lately, letting an LLM truly see a codebase.
If you haven’t met ReScript before, this one’s still worth watching . It has a clear case of how localized MCP servers can lift developer tooling.

We're Antifa. We are 10000% antifascist. We deplore fascism.
Seems it's a bad thing to be antifascist under a fascist.
They're admitting they're fascists.
Antifa isn't a group. It's a defense mechanism. It only exists because fascism exists.

They want to decide what books you can read, what history your children can learn, what medicines you’re allowed to take, what surgeries you can have, what gender you’re permitted to be, what sports you can play, which bathroom you can use, who you can love, and who you can marry. They want to own your library, your classroom, your hospital room, your bedroom—and now your television. They want to own the page, the pill, the joke, the chant, the kiss, the very pronoun in your mouth. And then, with breathtaking cynicism, they’ll look straight at you and say it’s the Democrats who are coming for your freedom. Small government? My fucking ass. This isn’t small government. This is government in your bloodstream, in your dictionary, in your bed, and now in your goddamn remote control.

I’m eating lab grown meat the second it’s mass market ready. It’s biologically identical to animal meat and will reduce suffering more than any technology in the history of our planet as long as enough people switch over from factory farmed meats.
