When you build with desktop-era frameworks, to desktop resource limits, only occasionally (if ever) marking your experience to the market reality of the median or P90 device, you lay down a structurally broken experience, one brick at a time.

Browser DevTools (including Chrome's) don't do nearly enough to highlight how bad the situation really is, and how deeply unrepresentative the developer devices are, even when "emulating" slower CPUs & Networks.

Free idea: there should be a service like BrowserStack that builds a DevTools extension that lets you subscribe to see/experience your dev environment on real hardware by default. Opening DevTools should never reflect your local device capabilities by default.

Was thinking about this after your talk. One thing that would be AMAZINGLY helpful is if the Chrome DevTools shipped with a Median Device Mode, which opened the page in Chrome on a median Android device w a median data connection in a dc somewhere (tunneling to localhost).

This would be great! Years ago, I asked DevTools team for this, and if not possible, enabling existing (low-fidelity) CPU and network throttling when a device is selected to emulate. Was told "no" so often I stopped asking. /cc

It’s not “nobody” but I agree that it’s Sturgeon’s Law in action; 90% of responsive sites are crap because 90% of websites are crap because 90% of everything is crap.https://adactio.com/notes/15934

Explicitly added the "~" to account for the rounding error fraction of folks who are doing it right. Most build in & for desktop context and fail to do mobile-first. They aren't doing RWD as you and I understand it, but they call it that. The words were stripped of intent.

It really doesn’t help that we have almost zero web dev tools on mobile. One thing that pushes this desktop centric view of development is the fact that dev tools are tethered back to the desktop instead of being on the device.

We need to start thinking about "browser emulators" much like native mobile developers have their runtime emulators integrating with their developer tools. Tools like https://sizzy.app or https://marketplace.visualstudio.com/items?itemName=auchenberg.vscode-browser-preview … are good starting points.
