No, not by a long shot. Remember how much time it took for an elaborate Flash animation to load? Sometimes you had to wait for more than a minute before anything even rendered on the page.
And Java applets.. were a joke. A Frankenstein approach to embedding applications in the browser.
By contrast, Wasm IS Javascript, even if the source code might be from another language, it's a target for compilation. It will only be able to do whatever the browser allows it to do, ie access Web APIs, work with the DOM or just do computations that don't output anything UI-wise.
This is not the return of badly executed and badly thought-out plugins, this is "native applications in the browser" done right.
Macs have always been throttled frying pans. They sacrifice much performance for the sake of thinness and design.
No wonder Flash always performed badly on mac devices.
>I am however scared that HTML will go the way of Gopher. Why would anyone care to maintain boring hypertext documents when we can have app of the day.
JS or Wasm can't create documents by themselves, they still need a DOM. Even if it's a 2D canvas or some WebGL canvas, it's still a DOM element. Or even if it's just an iframe that loads some blob, on the top level it's still a DOM element. And as such it can be inspected and controlled.
Simple as that. And his anger shows that he's frustrated for not managing to score goodboi points with the global media and public opinion. If you really only cared about the outcome (saving the kids), you'd be more modest.
But he only cared about his image, hence his frustration and name-calling.
