It is very likely that ARM-based Macs will lack a performant hypervisor upon release. We will have to see how VMWare responds. I'd bet it will inspire new products and innovation and the desktop space will move towards a less x86-x64 centric world. In the end it is a short term problem. Someone will respond and provide a performant hypervisor that can run on an ARM host and virtualize x86-x64 and ARM guests.

It's true it will cause some pain in the first year or two, but even as a heavy VMWare Fusion user I am really looking forward to the benefits of a vertically integrated laptop.

> Why can't you update the Docker image to also support ARM? You theoretically could switch your backend to run ARM Linux. However, this would take months - renting out ARM instances, re-building all repositories, and a tense switch over. I don't see why this would be so hard. If anything, I expect to see a massive upswing in things like AWS Graviton2 uptake, and a lot of common Docker images being built with ARM ver…

I'm kinda thankful to Apple for biting the bullet on this one. For whatever reason people will move mountains for Apple where other companies' products would just languish and die. The second order effects of ARM being something that's "safe" for people to use should be great!

VMWare did have a hypervisor for Raspberry Pi.

I'm not a heavy docker user but why can't I develop docker containers on Arm (as native containers, no emulation) and deploy to x86_64? Or vice versa? I understand that some packages are binary only and wouldn't be necessarily available for Arm, especially initially, but the majority should be.

Earlier quoted context omitted.

>>> expect ... a lot of common Docker images being built with ARM versions out of the box. This has no chance of happening. The common cloud CI systems do not support ARM at all (travis, circle CI and co). There is only a minority of developers with macbook and the rest is not going to spend $2000 to buy one just to build some docker images.

They will. Trust me. And you can buy a cluster of RPis to build your images for $2000

It's ludicrous to assume that anybody has $2000 to spend on fantasy hardware. It's month of disposable income outside of the SV bubble.

Better question might be, how many of the most common open source projects are managed by volunteers in their spare time? These will not build for ARM, unless there is a free tool doing it automatically for them. Currently GitHub + travis/circle can do for x64 on every push to master.
