That doesn't really make sense, if anything the importance of having third party cards is diminishing. Apple Silicon is already massively competitive at running things like Blender and Video Compositors. And the trends are towards apple investing in improving gaming and ML workloads (which they've made large strides towards this year), and the relative attractiveness of other GPUs is going down. Almost all of the signs are pointing at apple making their hardware the place to run on device ml.
