one of the reasons I rarely read press releases is that I don't believe in promises -- I believe in _incentives_. In this case, what will Qualcomm be incentivized to do? What are in their interests?
However the danger is that the language sees wide adoption but nobody uses it with Qualcomm hardware. Instead it might encourage people to buy AMD. This is a terrible outcome for Qualcomm. They paid to boost someone else's sales.
So the incentive is to make sure it runs best on Qualcomm and to at least slightly hobble other hardware. But the safest thing overall is to support Nvidia, Qualcomm, and that's it.
