People moan about C yet I find the web stack greatly more painful to write because you didn't even have control over the compiler following standards strictly (where stuff has even been standardised).
I really do wish we worked together to create a new standard for building and deploying documents and applications over the internet because this HTML (and all its supporting technologies) is an experiment that has gone bad. Id preferably want something that doesn't allow each browser to interpret the specifications differently and absolutely something that isn't controlled by Google (they would obviously need input but the last thing we need is another AMP).
Of course it will never happen, but one can dream / rant nonetheless.
There have been other examples in history where programming languages used to differ - sometimes even significantly - depending on which compiler / platform you were targeting and where a standards body later stepped in to create a basic subset of said language that should be universal across all dialects (please note they cannot enforce this). In those instances that has lead to code to become greatly more portable.
To some extent, this is now happening with the web as well; however my secondary point to the complaint about differing outputs between browsers is that I believe HTML et al is a lousy way to design applications from the outset. That definitely is not a problem created by warring proprietary vendors or slow revisions of standards but rather just an artefact of technology evolving past it's original purpose yet still having to retain backwards compatibility. Maybe the time has come that we need a second language for the web so we have HTML et al for legacy applications, blogs and other stuff that is following some of the original visions of the web, but have a new language for web applications and anything that requires a stronger security model.
It's amazing if you look at it from that point. You can't have security by default because the old standard is insecure by default (by todays means) and that's what legacy applications depend on, yet there has been a lot of progress that you can opt into.
My favorite example are cookies. While everything else is origin based, those are still based on a model that is very close to dns (everything psl+1 is the same thing). This opens you up to a large number of attacks, especially in a man in the middle situation (even with https). You can secure your own application by using secure cookie prefixes, but everything else is doomed.
Maybe it isn't great in all the ways, but at least it's something that works and is flexible enough for all sort of things.
I will grant you that things have gotten better in recent years and I do agree that there isn't such thing as a perfect solution, but given we're in an era where desktop software is being fazed out in favour of web applications (and even some desktop software is now being written using web technologies - such as Electron) it really feels like we're going wholesale into using a stack of technologies that could be significantly improved if we redesigned it from the ground up taking into account:
* what we have learned form the last ~25 years of the web,
* the change in how the internet (in a broader sense) is consumed over the last 10 years
* all the lessons we've learned from the decades of desktop software development.
Plus removing all the legacy cruft which your sibling commenter highlighted has to be seen as a bonus too.
I'm not suggesting we get rid of HTML entirely, but maybe have a new programming language for the modern web - like how we have different programming languages for other areas of computing for when we have different problems we are trying to solve. eg Bash, Perl, Go and C can all be used to write CLI tools but you'd use them to target different problems.
But as I said, this is just soapbox ranting. I couldn't see it changing without one of the powerhouses developing it largely in isolation and then we run the risk of walled gardens which - in my opinion at least - is worse than the current status quo.
