My initial reaction is that this reminiscent of the AMD-ATI deal back in 2006. It almost killed both companies and comparatively, this deal size is much bigger ($40B vs. $6B) for both a more mature industry and companies involved. $40B is an obscene lot of money objectively and what's the endgame for Nvidia? If it's to "fuse" ARM's top CPU designs with their GPU prowess, then couldn't they invest the money to restart their own CPU designs (e.g. Carmel)? My inner pessimist, as with others here, is that Nvidia will somehow cripple the ARM ecosystem or prioritize their own needs over those of other customers'. Perhaps an appropriate analogy is Qualcomm's IP licensing shenanigans and how they've crippled the non-iOS smartphone industry. That said, there's also examples of companies making these purchases with minimal insidious behavior and co-existing with their would-be competitors: Microsoft's acquisition of Github, Google's Pixel smartphones, Sony's camera lenses business and even Samsung, which supposedly firewalls its components teams so the best tech is available to whoever wants (and is willing to pay for it). I suppose if this acquisition ends up going through (big if), then we'll see Nvidia's true intent in 3-5 years.
