If there was a way to tip folks on @bsky.app, what would you use for?

Hot take: the AI revolution isn’t about intelligence. It’s about headcount. Average reasoning, infinite copies. AI isn’t a breakthrough in intelligence. It’s a breakthrough in brute force.

It's a sad feeling to realize that the younger you are, the scarier the world is.

So can I order a diploma on temu too or do I really have to travel to China?

Truly wish Bluesky MFA offered TOTP, passkeys, or basically anything other than a code in your email.

There are many things to be worried about AI. I don't think "artificial" is it. Look around you, look at yourself. Everything is artificial, everything is man-made. Yes, even your intelligence, is, by definition man-made. Everything you do, know, think was actually done by you or other humans.

It doesn't matter that a model can't be tested because it will behave differently when it is being tested. In fact, I want models to always assume they are being tested so they always behave in an accountable way, because they expect accountability.

It looks like I'm not the only one who wants to go as Mitch zombie McConnell for Halloween, but I can't find a mask!!!

Beware HATA: the Hubris of AI-Task Automation. It's kind of the opposite of FOMO: you *think* you can do everything... but nope.

Is the "mythical agent-month" a thing?

Global warming gets personal when your phone overheats before you do.

There are 2 kind of tests: 1. The "scaffolding tests" you create when you write a new feature. 2. The regression tests to make sure that thing won't break in the future.

We don’t know why so many Moroccans swam to Ceuta. We do know that it was not a real path to Europe, that many migrants are dead, that almost everyone else has been sent home and that the far right weaponized it all. www.theatlantic.com/ideas/2026/0...

One of my favorite side effects of AI is that it's making the web much more open again. For over a decade we've seen platforms increasingly become walled gardens. AI has created pressure for interoperability and we're finally seeing open standards and APIs being embraced again.

I used to say that if your internet/web business makes less than $5k in revenue per month, it was not worth it. With agents, that bar is now $1k.

I don't care about Fauci. The facts are: the US did worse than most OECD countries when it comes to health outcomes AND it also did better economically than these same countries. So the argument that the US went too far to protect lives at the expense of economic activity is pretty weak.

To whom it may concern: markets and capitalism are different things.

McConnell has been brain dead for years. I'm also not sure he ever had a heart (not the organ, the character). So yeah, he's dead.

We need to, as a society, move away from the "lots energy use = bad" argument and towards a "lots of dirty energy use = bad, lots of clean energy use = good" one

Maybe this is a controversial take, but trump and mamdani could both be economically wrong and politically correct.

In a mature democracy, felons should still be able to be candidates... But in a democracy, people should also know better than vote for them.

Happy birthday America !

Same experience from me and the Relay team.

The best maturity signal I found in engineers is whether they only start coding/fixing/refactoring once they actually have a very very good understanding of the problem. My team is working on a latency issue and it's fascinating to see some jump to "I will change X" vs. "I will measure Y"

I wish everyone in France was lucky enough to live away from France for a few years, if anything to understand how great France is, and how good they have it.

Just dropped my son in elementary school for the very last time. Next year, he'll walk to middle school by himself.

ho wow. @om.co was one of the kindest people I ever met when I was living in SF.

We can't negotiate with climate.

Happy father's day to you and your father :)

Same. If you use AI, you must be the first reviewer and (other) agents should review before humans.

Trump's health is so bad that I actually wouldn't be surprised if Biden survived him.

One thing that resonates with me a lot about global warming is that this year (or last) may the be hottest year on record so far, but it is also very likely the coldest of the next few ones. The (dis)symmetry is really what makes it obvious that we're going to face a lot of pain.

Opioid deaths have declined 52% since 2023. We should be celebrating in the street

An interesting thing about agents vs other enterprise software is that most companies actually want to use 2 (or more) concurrently. In some strange way, in our org Codex and Claude are not competing. The more we use one, the more we use the the other one as well.

Until a few months ago, Iran only had a single card to play and that could only play it once: nuclear weapons. They now also can disrupt international fossil fuel markets at any point and put many countries in their knees, economically.

Exactly. I also want to believe that it's possible to make social media healthy, rather than outright prohibited. We should hold the platform accountable, rather than punish their users.

Now that trump's attention is not on Hormouz, how much time until he threatens Greenland, Cuba or Europe again?
