I think they assuming from the past that this will happen. When Apple moved from powerPC to x86 there was Rosetta 1. It got deprecated as well.

I think it is different this time. A lot of developers use Rosetta 2 for Linux to run x86-64 Linux Docker containers under macOS (including me). They'll be upset if Apple discontinues Rosetta 2 for Linux. By contrast, once the PPC-to-Intel transition was under way, Rosetta was only used for running old software, and as time went by that software became increasingly outdated and use of it declined. While I think Rosetta 2 for macOS usage will likely decline over time too, I think Rosetta 2 for Linux usage is going to be much more stable and Apple will likely maintain it for a lot longer. Maybe if we eventually see a gradual migration of data centres from x86-64 to ARM, Rosetta 2 for Linux usage might begin to also decline, and then Apple may actually kill it. But, if such a migration happens, it is going to take a decade or more for us to get there.

    I just pointed out what happened in the past. I have no clue if Apple will deprecate it and what reason they put forward doing so. I personally like the fact that I can run both arm and x86 binaries. But I think judging Apple that if they don’t have a personal reason to support Linux (they also use it for their services) they will remove it. But deprecated dons’t mean it will be removed anytime soon. Apple keeps APIs and frameworks as long as they don’t interfere with something else.

    What's the advantage of running x86-64 Linux Docker containers over running ARM Linux Docker containers? Aren't most distributionss and packages available for both platforms?

      Microsoft SQL Server is only available as an x86-64 docker container binary. They actually had a native(?) arm64 docker container under the name "azure-sql-edge", which was (and still is) super useful as you can run it "natively" in an arm64 qemu linux for example, but alas that version was not long lived, as Microsoft decided to stop developing it again, which feels like a huge step backwards.

      There's probably other closed-source linux software being distributed as amd64-only binaries (rosetta 2 for linux VMs isn't limited to docker containers).

      The advantage is the fact that they exist. Not every Docker container is built for multiple platforms.

      Lots and lots of Docker images are only linux/amd64 compatible. Without Rosetta 2 I wouldn't be able to do my job, especially in a team with a mix of Mac and Linux workstations and most images being build as amd64/linux only.

      Some images are only available for amd64 still. Like oracle databases. Even if there is an arm64 of a recent version of the app, it may not exist for older versions that you want to test against.

The first Rosetta was based on licensed technology, used at a time when Apple was still pinching pennies.

It made financial sense to stop paying the licensing fee to include it in each new version of the OS as quickly as possible.

There is no financial incentive to remove the current version of Rosetta, since it was developed in-house.
