No it's not, and we do have semantic web accessible to screen readers. It is just also this incredible universal platform for building and distributing applications. It's a universal layer accessible to all, no mater your socioeconomic background, politics or location.
Criticising the web platform as not confirming to a set of self defined rules is lazy and pointless.
Not the OP you replied to, but I've worked in about a dozen languages in 15+ years and I also think Javascript is fine. It will never be #1, but it does a good job for the things it is good at.
The fact that you mentioned Elm is funny to me as it is so low ranked in terms of usage or desire that it doesn't even show on StackOverflow's survey results.
We were so, so close to a semantic, reader-based web ~20 years ago.
The ad supported Internet killed it. Now that the ad supported Internet is dying, maybe we can get back to it.
