human brains are weirdos.

Truer words were never said. :)

the reason people post pictures of text is to give proper attribution, but also to distance themselves from the content,

If only we had some way to reference an original source. Something like a figurative link, if you will.

If only there was a way to copy text, and then paste it someplace else. Sigh… unsolved problems.

0. Getting users to post text instead of screenshots of text.

It would be interesting to see the annual global power consumption from design choices like this.

Looks like a promising effort. I just wish their notion of “first-class Qt support” included Qt Widgets.

Or, if they’re unwilling to do that, exposing in Qt Quick the missing functionality that has been available in Qt Widgets for ages.

Current web browser engines generally support JavaScript and WebAssembly, and no others (unless via a plugin, as with Java).

So, if I understand you correctly, your options are to find a language that transpiles down to one of those two (several such languages exist), or find an engine that isn’t precisely a web engine but supports some alternative language(s). I don’t know any useful examples of the latter, but perhaps someone else will chime in with something like that.

Can you clarify what you’re asking for?

If you mean a web browser that isn’t based on Firefox or Chromium, the Ladybird project might fit.

If you mean a web-like platform that doesn’t use fancy things like JavaScript, HTML and CSS, there is Gemini.

Do you mean something else?

Maybe webm and mp4 files with multiple language tracks are usually played with a media player, not a web browser?
