+\frame{\frametitle{Why another Vector Extension?}
+
+ \begin{itemize}
+   \item RVV very heavy-duty (excellent for supercomputing)\vspace{10pt}
+   \item Simple-V abstracts parallelism (based on best of RVV)\vspace{10pt}
+   \item Graded levels: hardware or software-emulation\vspace{10pt}
+   \item Even Compressed instructions become vectorised\vspace{10pt}
+  \end{itemize}
+  What Simple-V is not:\vspace{12pt}
+   \begin{itemize}
+   \item A full supercomputer-level Vector Proposal\vspace{12pt}
+   \item A replacement for RVV (designed to be augmented)\vspace{12pt}

+\frame{\frametitle{Quick refresher on SIMD}
+
+ \begin{itemize}
+   \item SIMD very easy to implement\vspace{10pt}
+   \item Parallelism is in the ALU\vspace{10pt}
+   \item Negligeable impact for rest of core\vspace{10pt}
+  \end{itemize}
+  Where SIMD Goes Wrong:\vspace{12pt}
+   \begin{itemize}
+   \item See "Why SIMD considered harmful"\vspace{12pt}
+   \item (Corner-cases alone are extremely complex)\vspace{12pt}
+   \item O($N^{6}$) ISA proliferation\vspace{12pt}
