By 2017, you have higher chances of seeing Apples own ARM silicon under the hood of their low power notebooks than AMD being there. If they built in a static re-compiler for X86 on ARM (Talking Kernel level, not some shoddy software) people could run all their favorite software on an ARM Macbook. Personally with how iOS is going, I could very well see this happening within the turn of 2020. Just as they had done with PowerPC back in 2004/2005. Sure it would be ugly at first, but people would get used to it.
