Of course. Any time you try to run a non-ARM binary on an ARM CPU without some form of translation or emulation, it will fail. This is also true for any other CPU architecture. If you want to know about specific compatibility issues, I'm happy to try to help as I've been using an M1 Air as my daily driver for many months now.

Did they finally get Docker working on the M1 chips?

  Docker works mostly fine. ARM images are pretty common, and for those that don't have it, it runs a QEMU emulated x86 machine. I have hit issues with it but they're rare enough that I don't care.

  Native ARM containers work but there are various things that break with Docker x86 emulation, eg with Node.

  It’s somewhat unreliable and file system interaction is slow, but from what I’ve heard that means it’s no different from x86 Docker Desktop.

  Mostly. Docker for Mac's internal VM consistently kernel panics the first time I launch it after a reboot. I also have containers freeze up every now and then, something that never happened on my Intel machine.

  I don't think I've ever had an issue related to Rosetta2. Everything I had to run on it worked flawlessly and without any noticeable performance hit. This is only my own anecdote though.

    There have been some font rendering issues in Ultimaker Cura (which is written in Python) that ran as x86 on M1. These have been resolved in the Python library.

      In fairness, I've seen font rendering in Cura on Linux as well.

        I've seen font rendering issues in Cura on Intel Macs as well. Cura's GUI and UX are pretty bad in general IMO though, so I don't use it.

    I also had everything working fine but performance is really bad when you go through rosetta. For example, discord client is still x86 and while it works without any issues, the heaviness is noticeable. Also, .NET 5 does not have an arm build (.NET 6 does but it is still in beta). The entire toolchain works but compiling a binary can be 3-4 times slower on the emulated one. Things work without any issues though. They are just slow.

You’re missing the point, it’s an ecosystem question. I personally don’t experience many issues at all. If I do they’re usually solved by switching to Rosetta (but that does introduce some hairiness for command line stuff).
