You keep saying this, but this still does not match the reality that Nvidia has bid a lot of money for ARM.
So there must be something "in" for them that makes it worth it for them to pay 40 billion dollars.
The claim that this deal will be a disaster for ARM is IMO equivalent to saying that "killing ARM is worth 40 billion dollars to NVIDIA".
That makes no sense, at all. The only reason ARM is worth 40 billion dollars is because of its users. If ARM loses its user base, it is worth as much as MIPS or OpenPOWER (aka 0 dollars).
Also, if ARM loses its user base, NVIDIA ARM CPUs become worthless.
I have a hard time believing that, after investing 15 years of R&D into their own ARM CPUs and finally shipping serious ARM CPUs to market, NVIDIA would pay 40 billions to make that all worthless.
