'I don't think there is any programming language that is "unditchable".'
There can not exist one perfect programming language for all uses. (Sometimes people don't like that statement but I think if you seriously sit down and work the math it's pretty obvious that, as a simple for instance, Rust is not going to replace all shell scripting and shell scripting is not going to replace all Rust, and that's just an example, the principle holds in numerous dimensions in the programming language space. [1])
There are always people making bad decisions, some of those bad decisions are about which programming language to adopt for a problem.
So, yes, you'll always be able to find companies dropping some language, but it isn't necessarily the language's "fault".
I don't say this on every such article in the comments because it's kinda kicking someone while they're down, but I would assess that the clear majority of the ever-present torrent of "We switched from X to Y and look how much better Y is!" are actually long and detailed explanations of how the company in question chose the wrong technology for their problem, not how bad X is. The two major exceptions are "our tech in X predates Y existing as a valid choice, and now that it does, it's a better choice" (can't blame them for existing before the right tech, I've made that move myself in my own career) and "We did our research and X really should have worked but we got into it only to discover that it really didn't for some reason we could not have reasonably anticipated". That latter is pretty rare, IMHO, but I've seen it a couple of times. (Generally it is when a closed-source stack has a fundamental problem and you can't fix it, because it's closed source.)
(I suppose there's also "X was a good choice initially but we outgrew it", but in my very opinionated opinion even these are often... dubious. It happens, yeah, but in my personal opinion it still means the language chosen was not able to scale the solution. Only people truly suprised by their growth, which does happen, should reach for this.)
[1]: And if that still bothers you, think small shell rather than large. I'm not going to write Rust for the equivalent of "awk '{ print $3 }' myfile | sort | gzip > sorted_names.gz". However broken shell legitimately is as a programming language, you simply can not argue with that kind of bang-for-the-buck.
