Then you have Metals for VSCode InteliJ plugins, while the Eclipse plugin was dropped.
InteliJ plugin is much further than Metals, however there is the conflict of interests with pushing Kotlin instead.
Meanwhile most Scala shops have pivoted to also give feature parity on modern Java, and Kotlin, thus reducing the interest in using Scala in first place.
However as mentioned, they are doing cool stuff with capabilities at EPFL for Scala 3.
All three major programming environments at Xerox PARC, shared similar concepts.
Interlisp-D, Smalltalk, Mesa (XDE) which evolved into Cedar.
If you read Xerox papers about all of them, there are several quotes on how relevant it was to share the same programming experience across environments.
Which is why, given their linage, JVM and CLR are the closest big mindshare ecosystems that somehow still have traces of those features when using their IDEs and runtimes, even without being a proper Smalltalk or Lisp.
The nice thing about Swift, or Java/Kotlin on Android, is the platform owner attitude, either adopt it, or go elsewhere, that is the only way safety improvements are pushed into mainstream.
> A common refrain is that Emacs is an operating system (OS). This isn’t true, but what invites comparison to an OS is its ability to orchestrate applications and utilities above the OS kernel level.
Only because Lisp Machines, or variations thereof didn't took off in the mainstream.
Because they killed the market, no one would now buy a macOS server, when Linux distributions, and to a lesser extent FreeBSD, own the server room.
They would even sell less than Windows Server licenses.
By the way, they are down the same path with the workstation market, now that they only top level answer is the Mac Studio.
Workstation market wants flexible towers that they can customise to their own liking and special use cases.
The main reason Swift exists for Linux, is that app developers need to have servers somewhere, and if they want to share Swift code with the backend, well it isn't going to be on macOS Server.
> Apple's Mac mini and Mac Studio have become the machines of choice for running AI agents, according to Doug Brooks, Apple's senior product manager of Apple silicon.
This is mostly an US phenomenon, no Mac mini nor Mac Studio around here.
Only Thinkpads and Macbooks laptops talking to hyperscalers.
