Quick responses, sorry.

• gaming is a problem for people who DO want this type of machine, and not a second or console. It's only become an issue with M*
• Apple has literally thrown an entire engineering group behind their ability to import, export, and transcode media. So much so they even have their own fork of ffmpeg. It's atrocious.
• PyTorch is CPU with GPU acceleration where applicable, and most devs want direct GPU access. Not possible on Apple hardware. LLMs are kinda dumb, and most people work on imaging inference. Direct access to the hardware for local development is a must.
• Not sure what you mean, but Rosetta is essentially QEMU emulation, which is insanely slow. I can run a 2m build for something on a native x64 machine, or a 1 hour build through Rosetta. No thanks.
• This is a power play by Apple thinking people will still buy their stuff and just deal with the inconveniences, but turns out the sales numbers show that is not the case.

In general, the "use containers for everything" is not a good workflow. It's also very subjective to performance on the platform you run it on. Containers all the time is exhausting and problematic for a number of different reasons.
