  \begin{itemize}
-   \item Goal is to create a mass-volume low-power embedded SoC suitable
-         for use in netbooks, chromebooks, tablets, smartphones, IoT SBCs.
-   \item No way we could implement a project of this magnitude without
-         nmigen (being able to use python OO to  HDL)
-   \item Collaboration with OpenPOWER Foundation and Members absolutely
-         essential. No short-cuts.  Standards to be developed and ratified
-         so that everyone benefits.
-   \item Riding the wave of huge stability of OpenPOWER ecosystem
-   \item Greatly simplified open 3D and Video drivers reduces product
-         development costs for customers
-   \item It also happens to be fascinating, deeply rewarding technically
-         challenging, and funded by NLnet
-
+   \item SIMD fundamentally assumes element independence.
+   \item No provision in SIMD ISAs or Architectures for
+         inter-element inter-dependence, let alone sequential
+         inter-dependence.
+   \item Simple-V adds features such as Data-Dependent
+         Fail-First as \textit{general concepts},
+         exploiting Condition Registers (Vectorised)
+   \item Hardware Parallelism is \textit{still possible}
+         by exploiting the standard capabilities of
+         Speculative Execution: produce results, hold
+         off writing, post-analyse and cancel the results
+         that should not be written. Uses \textit{existing}
+         standard OoO Micro-architecture
+   \item Huge simplification of algorithms, huge "compactification"
+         just like Zilog Z80 and Intel 8086, yet still parallel
+   \item compact deep-expressive assembler brings CISC
+         capability but RISC-RISC (Prefix-Suffix). SIMD remains
+         at the \textit{back-end in hardware} where it belongs.
+         Not exposed at the programmer.
