I recognize it as a more or less universal optimization process. Everything important ends up in silicon, if it remains important long enough. And there are several stages of that.

Like you, a part of me years for SGML and The Semantic Web, and where it makes sense in Alumina I am using RESTish APIs.

But I do not pine for Javascript. Language or frameworks. 20 years has been enough. And I do not believe that some of the 4mb minified obfuscated js downloads from a CDN I've seen are in any way more accessible than a WASM binary of similar size. At least there is advanced tooling for the WASM representation. Folks who want you to read their code will still make it easy, and folks who don't won't.

To your point about learning, WASM makes some really incredible systems like https://lovr.org/ available in the browser, which I would have loved to have as a kid, but which also aren't javascript. It's related to Turing completeness somehow, once you let a little software into your structured document, it all wants in. Or maybe it's "if you give a mouse a cookie"?

I understand what you're saying about discoverability. But the developer in me really likes having a relatively simple binary interpreter to target for network-delivered cross-platform binary applications. My hope is that offering such a juicy target to the folks who want to develop applications (including myself) gets them out of all the semantic document features, allowing both sets of code to get simpler and more focused. Because I think they're two different, both entirely valid, tasks folks use the web for.
