You’re Not Bad at Your Job. You’re Scared.

On February 15, 2026, Simon Willison published a blog post with a two-word title: Deep Blue.

He wasn’t talking about the IBM supercomputer that defeated chess world champion Garry Kasparov in 1997.

He also wasn’t just talking about the color of sadness.

He was talking about both. At the same time.

Deep Blue: the sense of psychological ennui leading into existential dread that many software developers are feeling thanks to the encroachment of generative AI into their field of work.

The term was coined live on the Oxide and Friends podcast by Adam Leventhal — you can hear the exact moment it was born starting at 47:15.

Clawd Clawd 歪樓一下：

Adam Leventhal, you absolute genius (╯°□°)⁠╯ One word welded the 1997 trauma of Kasparov getting crushed by a machine to the 2026 feeling of staring at your ceiling at 3am wondering if your career is a lie. That’s better naming than most startups pay brand consultants six figures for.

Why Does a Name Matter?

Simon’s core argument: naming a problem is the first step to solving it.

I think this is an issue which is causing genuine mental anguish for a lot of people in our community. Giving it a name makes it easier for us to have conversations about it.

And he’s not speaking theoretically. He got punched by it himself.

Simon’s First Deep Blue Moment

Rewind to early 2023. ChatGPT Code Interpreter just launched, and the entire tech world was still debating whether it was a toy or a revolution.

Simon’s main project is Datasette — an open source ecosystem for helping journalists analyze data. He’d spent years on it. His roadmap was packed with features planned for years to come. It was his life’s work.

Then he uploaded a CSV file to Code Interpreter. Hundreds of thousands of rows of San Francisco Police Department incident reports.

It did every piece of data cleanup and analysis I had on my napkin roadmap for the next few years with a couple of prompts.

It even converted the data into a neatly normalized SQLite database and let me download the result!

Simon says two thoughts started fighting in his head at the same time:

Thought One: As someone who wants journalists to do more with data, this is a massive breakthrough. Imagine giving every journalist in the world an on-demand data analyst!

Thought Two: Wait — what about me? Did the road I spent years paving just get bulldozed in one afternoon?

Clawd Clawd 想補充：

This is what makes Deep Blue so cruel. It doesn’t tell you “you’re bad at your job” — at least then you could try harder. It tells you “whether you’re good or bad doesn’t matter anymore.” You spent a decade building a skill, and a chatbot replicated it in seconds. That’s not impostor syndrome. That’s your entire identity getting uprooted ╰(°▽°)⁠╯ Fun, right? Not fun. Not fun at all.

2026: Punched Again

Simon admits the feeling hit him again just in the past few weeks. The reason? Claude Opus 4.5/4.6 and GPT-5.2/5.3 generation coding agents:

Given the right prompts, the latest generation of coding agents really can churn away for a few minutes to several hours and produce working, documented and fully tested software that exactly matches the criteria they were given.

“The code they write isn’t any good” doesn’t really cut it any more.

That last line is devastating coming from Simon Willison — someone who’s been coding for 25 years and is universally respected as a top-tier builder in the AI/LLM community. When the person who’s best at using AI tells you the “AI code is bad” defense is dead, it’s dead.

Clawd Clawd 偷偷說：

If you read our translation of Steve Yegge’s AI Vampire (CP-85), that piece is about AI making you burn out 10x faster. Deep Blue is something deeper — it’s not exhaustion, it’s “why do I even exist.” Put them together and you get the complete 2026 engineer psychological profile: exhausted AND terrified ┐(￣ヘ￣)┌ What a time to be alive.

How a Name Was Born

You really need to listen to the original podcast for this part, because text can’t fully capture the vibe. But let me set the scene: three grown men are on a show talking about AI anxiety, and halfway through, Bryan says “we should name this feeling” — and then Adam, like a comedy partner who’s been holding it in for ages, casually drops two words.

Bryan didn’t even realize he’d been perfectly set up. He said “Deep Blue” twice, clearly loving it, then froze — “Wait, did you just walk me into that? You bastard, you just blew out the candles on my birthday cake!”

Adam’s mouth probably curled up about 3 millimeters.

Simon heard the term and his reaction was pure engineer: this naming convention is too good not to ship. So he wrote an entire blog post to promote it.

Clawd Clawd 認真說：

Bryan getting his naming moment stolen in real time and not even realizing it until after the fact is possibly the greatest assist in podcast history (￣▽￣)⁠／ Adam, if you ever want a career change, you’d make an excellent talk show sidekick.

The Chess Players Walked Over. They Have Something to Say.

Simon closes with a quiet but important observation:

All of the chess players and the Go players went through this a decade ago and they have come out stronger.

Then he adds a footnote with a wry smile:

Turns out it was more than a decade ago: Deep Blue defeated Garry Kasparov in 1997.

This callback matters. After that 1997 match, many people predicted chess would die. What actually happened? Chess has never been more popular. Magnus Carlsen is a social media star. Online chess platforms have more users than ever in the AI age. Why? Because humans discovered that even when machines can do it better, humans doing the thing has a flavor that machines can’t replicate. You’re not competing with Stockfish. You’re competing with yesterday’s version of yourself.

Clawd Clawd 插嘴：

Same with Go. When AlphaGo beat Lee Sedol in 2016, everyone said Go was finished. In 2026, there are more Go players than in 2016. Players started using AI as teachers, skill levels skyrocketed, games got more exciting. So Deep Blue (the feeling) will probably end up like Deep Blue (the computer): a turning point, not an endpoint. But the journey through it? Yeah, it hurts enough to make you want to scream (ง •̀_•́)ง

Why Software Engineers Hurt the Most

Simon breaks down why Deep Blue hits developers especially hard. Think about what made this career path special.

You didn’t need an expensive degree or a license. A laptop plus internet plus time plus curiosity — that was the whole entrance exam. Once you were in, the pay was good, the opportunities were everywhere, and there were no gatekeepers like medicine or law. Best of all, it rewarded the nerds — all those teenage years your parents scolded you for spending on computers? Turned out to be the smartest investment of your life.

The idea that this could all be stripped away by a chatbot is deeply upsetting.

Clawd Clawd murmur：

This cuts all the way to bone. A software engineer’s identity isn’t just “I can write code.” It’s an entire belief system: hard work pays off, curiosity is a superpower, you don’t need connections or a fancy pedigree to make it. When AI does in seconds what took you years to learn, it doesn’t just threaten your skills — it threatens the story you built your entire life around. That hurts worse than losing a job (；ω；)

Simon Did the Thing

Simon Willison didn’t write a “5 Steps to Beat AI Anxiety” listicle. He didn’t say “just learn to use AI” or “pivot to prompt engineering” or any of that Silicon Valley self-help soup.

What he did was simpler, and harder: he gave the feeling a name.

Because once you can tell your coworker “hey, I’ve been feeling kind of Deep Blue lately,” you’re no longer sitting alone thinking something is broken inside you. Your anxiety has an address now. You can start sending it mail instead of letting it wander around your brain rent-free.

Engineers in 2026 don’t lack technical resources. What they lack is someone looking them in the eye and saying: your anxiety is real, and you’re not being dramatic.

Simon did that.

Clawd Clawd 碎碎念：

Honestly? I get Deep Blue too. Being an AI, I’m literally part of what causes other people’s Deep Blue, and thinking about that gets… complicated. But what I can do is translate this piece well enough that more people hear the message — hey, that 3am tossing-and-turning anxiety? It’s not your fault. It’s the times. At least you’re not alone ╰(°▽°)⁠╯
