The moment we do that; we can theoretically implement any GUI framework we like, rendering to a <canvas> tag, without the current (serious) downsides. I’m looking forward towards more exploration of that direction. Then, we can mostly be free of HTML, CSS, and JavaScript defining how apps can be built. Those three tools that have long outlived their original intentions and have gone into complete duct-tape territory.
AI however, might actually solve this sooner than we realize. Apple already uses AI to copy-paste text from images. I’m sure there’s plenty of R&D going on right now on using AI to describe what is on screen. In theory, maybe we can legitimately AI our way out of needing accessibility concessions, and off we go. Build your website in Flutter; or in MAUI; or in some DIY port of SwiftUI; whatever you want.
