 **Of all of these, the only one with the most going for it is the Power ISA.**
+
+The summary of advantages, then, of the Power ISA is that:
+
+* It has a 25-year software ecosystem, with RHEL, Fedora, Debian
+  and more.
+* IBM's extensive 20+ years of patents is available, royalty-free,
+  to protect implementors as long as they are also members of the
+  OpenPOWER Foundation
+* IBM designed and maintained the Power ISA as a Supercomputing
+  class ISA from its inception.
+* Coherent distributed memory access is possible through OpenCAPI
+* Extensions to the Power ISA may be submitted through an External
+  RFC Process that does not require membership of OPF.
+
+From this strong base, the next step is: how to leverage this
+foundation to take a leap forward in performance and performance/watt,
+*without* losing all the advantages of an ubiquitous software ecosystem?
