They probably love the idea: Replace you're functional buy virus ridden Intel CPU based Windows PC with a ARM based tablet that 'can run full windows 10'. Wait 2 days until the buy realizes that emulating x86 on ARM is absolutely shitastic and that the whole thing is a retarded idea, they'll return the stupid ARM 'pc'
When intel cares, they'll do something about it. They can make ARM processors (Intel even did at one point, think they stopped) as good as anyone
Intel missed mobile by dumping ARM, but ARM isn't going to replace real processors anytime soon for servers that do real work. Sure, it might replace the one dinky little server that some company puts a website on that should have been a VM on some cloud, but thats not exactly a high dollar market right there nor is it more than a handful of people.
ARM server CPUs will not be anything like what you think of as 'ARM' CPUs, at which point, they'll be a lot more like Intel CPUs with the same performance and issues.
ARM CPUs are built for different purposes than x86 CPUs. They will never have the exact same level of capabilities and you'll never use them interchangeably.
ARM CPUs from different fabs can be used the interchangeably because they ARE the same CPU. Its all from the same initial designs, just different configurations. A Qualcomm ARM CPU is never going to be ridiculously better than a Samsung ARM CPU because they are both ARM designs, same cores, same roots, same everything, hell in reality, probably Fab'd in the same plant on the same production lines!
