Yes, I’m talking about Sam Altman. daringfireball.net/linked/2026/...

The problem is not that he claims his team could see into an unknown future. It’s that it’s so easy for Americans to think Feb 2020 was “before”, when it was very much after.

The COVID-19 pandemic started in 2019.

And we still believe deep in our souls that white Americans are the center of the universe. Especially men. Everyone else is nothing. Literally nothing.

Turns out, 99% of people here would rather kill someone else than be personally uncomfortable. Turns out, people do not believe in science. Turns out, literally no one cares about other people. We turn narcissists into Gods. Reward liars with power.

And the collective hallucinatory 🤬 in the U.S. continues. “Covid is mild.” “The pandemic is over.” “Getting sick strengthens your immune system.” “It’s normal to feel all these symptoms, that’s immunity debt.” “Kids are safe.”

These are all lies. Fed by arrogance & selfishness. Utter lies.

I mean, I started trying to warn all of you on Twitter on Feb 24. It was definitely completely obvious to anyone watching news from actual reporters outside the U.S.

If we hadn’t had idiots for political leaders (local + national), I would not have been on that plane. Or at least not without wearing the N95 mask I’d almost bought but didn’t because “save them for healthcare workers”. I was definitely no genius.

I knew in mid-Jan 2020. And watched news from Singapore daily for weeks. That’s why I stocked up on food & supplies late Jan – mid Feb and went into lockdown Feb 27. If I hadn’t been required by other people to get on a plane March 3rd, I wouldn’t have spent the last 6 years sick & disabled.

Becoming “obsessed” with Covid in late Jan/early Feb 2020 is not “before the rest of the world” — unless you believe the only country in the world that matters is the U.S.

Literally billions of people knew then. Claiming GENIUS for simply watching news from Asia is peak white American superiority.

Name-Only Containers: The Scoping We Needed If we give a `container-name` to the root of all our unique components, we can scope styles to them with a simple @container query.

We definitely are NOT ignoring this. I just don’t have anything to share yet.

Using Claude Code feels like playing SimCity.

I don’t have any timing to share at the moment. Keep an eye on Safari Technology Preview and Safari beta release notes.

The COVID-19 pandemic is not over, the effects of SARS-CoV-2 are commonly body-destroying in ways we’re barely beginning to understand, and the best way to keep yourself and others safe is to WEAR A MASK.

oh heck yes I don't need to bother fixing this bug now

WebKit Features for Safari 26.4 March has a way of bringing a lot of new things to WebKit — and this year is no exception.

Safari 26.4 is here!
webkit.org/blog/17862/w...

Grid Lanes. WebTransport. Keyboard Lock API. And _tons_ of fixes & improvements. Please read the introduction to our article to learn what we’ve been up to…

Safari compact tabs are back 😌

Also, very many quality fixes -- my favorite kind of work.

Nice improvements to scoped custom elements registries!

Grid Lanes!! I can’t wait to use this everywhere

ECMAScript excitement 😉

Safari 26.4 ships support for @tc39.es Stage 4 Iterator.concat 🎉

It creates a new iterator by sequencing existing iterators.

We are passionate about making experiences our customers love, no matter how they use their device. Web designers and developers are central to those experiences. You are our partners. We truly hope this release makes a real difference in your success.

Every rendering fix, every improved feature, every performance gain we ship benefits everything touched by the web platform.

When our customers open a news app, a shopping app, a travel app, a banking app — there’s a good chance the interface they’re interacting with is powered by the same HTML, CSS, and JavaScript you write every day when making web apps and websites that live at a URL.

We care deeply about the experience people have when using Safari. And we care about the experience people have when using any of the millions of iOS, iPadOS, macOS, visionOS, and watchOS apps that are built using WebKit and JavaScriptCore.

We are paying attention, even if our response shows up as a shipped fix rather than a reply in the issue.

When multiple websites signal that something needs fixing, that helps. The more concrete you can be — a brief story about why this hurts your users, a link to a real website affected, a snippet of code or reduced test case — the better equipped we are to prioritize and fix what matters most.

As we continue, we greatly value your input. If something is bothering you, test in Safari 26.4 to see if it’s fixed. If the bug is still there, please file it at bugs.webkit.org. If it’s already filed, add comments to the existing issue describing your experience and why fixing it matters for you.

And we’re continuing our multi-year rewrite of the layout engine. Blocks-in-inline layout is complete in Safari 26.4, work on Flexbox continues, and we’ve now begun rewriting CSS Grid.

And then there are the bug fixes — hundreds of them across the platform. WebKit engineers went deep to improve specific areas like SVG, Tables, MathML, and CSS Zoom.
