One of my hopes for 2026 is that browser vendors take more responsibility for today's pervasively bad experiences. Nobody wants a slow site, but they also don't want to dismiss a mailing-list pop-up that blocks scrolling. Browsers need to step in:

The Performance Inequality Gap, 2026 - Infrequently Noted
Embedded in this year's network and device estimates is hopeful news about the trajectory of devices and networks. It has never been easier to deliver pages quickly, but we are not collectively…

Frontend is failing. 75% of devices with browsers are smartphones, but not even half of sites pass Core Web Vitals on them. Why not? Too much JavaScript, added to indulge SPA fantasies the data is falsifying in real time:

How's the mobile CPU landscape evolving? Thanks to process node improvements, a mid-range Android from 2025 is (finally!) as fast as 2017's iPhone 8, but a low-end (~$100) smartphone isn't yet as speedy as a decade-old iPhone 6s.

I stared into the abyss and 12MB of uncompressed JS, containing thousands of SVG icons, webpacked into cursed React components stared backed like a horrifying fractal of beady little eyes.

We need leaders on the web who understand the stakes. The wealth bubble has made a lot of these people extremely complacent, and over time, that seems to have dulled them...which makes it a mystery that they keep talking like they know things.

"iPad just isn't the same as a mac", and all that.
Then Nilay asks "What does a mac represent to you?"
David: "Desktop-class browsers."
Nilay: "You want Chrome! You want Chrome and Electron apps!"
In other words: competing browser engines on i(Pad)OS.

Yesterday at TPAC I publicized my draft proposal for adding a declarative templating API to the DOM.
github.com/justinfagnan...
The repo has:
📖 Explainers for the templating API and DOM scheduler API
🏗️ Full prototype implementations
⚗️ a JSX transform
⚛️ a mini React-like framework

There's still a lot to do on this to make it a real proposal and to document the motivation and rationale more thoroughly, but I think it's a good start.
I'm looking for feedback, suggestions, and co-champions if anyone out there is interested!

I tried to AI code some in-browser video decoding stuff. It made a mess.
So I learned the APIs somewhat properly, and did a much better job, but it was still messy.
Then I found mediabunny.dev and it just worked. Yay!

Well surely that's due to the Safari team sitting on their hands and being 5-8 years late in shipping it, and even now that it has, it's still quite gimped?
Burning out developer enthusiasm is the precise goal in Apple dragging their feet on web features after all.
