 # Why in the 2020s would you invent a new Vector ISA
+
+Inventing a new Scalar ISA from scratch is over a decade-long task including
+simulators and compilers: OpenRISC 1200 took 12 years to mature.
+A Vector or SIMD ISA to reach stable
+general-purpose auto-vectorisation compiler support has never been
+achieved in the history of computing, not with the combined resources of
+ARM, Intel, AMD, MIPS, Sun Microsystems, SGI, Cray, and many more.
+GPUs have ultra-specialist compilers, and standards managed by the
+Khronos Group, with multi-man-century development committment.
+
+Therefore it begs the question, why on earth would anyone consider this
+task?
