You install Linux. Seriously, if you have some money to donate, support the Asahi Linux project, especially if you want to do something that Apple does not want to on Apple Silicon platforms.
I follow Asahi Linux with great interest, because there is so much to learn from their work, but frankly, I have no interest in the delivery of the project. I have zero interest in running Linux natively since all my Linux needs are covered by Docker and virtual machines.
That said, I do think that Apple should implement PCIe to VM passthrough in their virtualization frameworks so that Linux machines can use eGPUs and other hardware.
Controversial take: Apple doesn't want to get into gaming not because they are prudes or ignorants or anything like that, but because they know they cannot win. People who want an easy-to-use experience in gaming are already on consoles, while hardcore gaming nerds will always choose PC because of extensibility and also prejudice against Apple products.
I think for sure they will expand their Arcade offer to try to use more of the M1 power, but it will always be an afterthought for them, never the mega gaming machine that half a dozen of people in the community want.
There is a huge range of possibilities between "getting into gaming" and building a "mega gaming machine". I mean, it is obvious that Apple is not likely to offer dedicated gaming devices. But it is also obvious that the new Macs have been designed to be good at a wide range of tasks, gaming included. If Apple did not care about gaming at all, as often claimed here, thy would not go through the trouble of integrating advanced gaming-oriented features into their hardware and APIs. Monterey even has a gaming focus mode if you connect a controller...
But yeah, I don't see Apple buying game studios and getting into gaming business directly. It's risky and there is not much benefit for them. Their gambit is offering state of the art hardware and software and hoping that this (along with the popularity of the new machines) will be incentive enough for developers to start thinking about high-quality Mac versions for their games.
