I always wonder where will x86 be in 10 or 20 years time. As data paths widen for SIMD, how many can they possibly cram even more generations of wider and wider groups of instruction with different opcodes and characteristics.
Do you remember the 1990s everlasting arguments about RISC vs CISC? There were so many arguments (online and magazines) saying that "soon" RISC would eat CISC. And yet, it never happened. I'll be dead before the demise of x86. More likely: The computing landscape will get more complex. Probably ARM will become a legitimate competitor to x86 outside of handheld computing, and RISC V will become a legitimate competitor to ARM for single board and handheld computing.
