+% We can start off with a couple of observations about the role of
+% compilers. First, hardware is getting weirder rather than getting
+% clocked faster: almost all processors are multicores and it looks
+% like there is increasing asymmetry in resources across
+% cores. Processors come with vector units, crypto accelerators, bit
+% twiddling instructions, and lots of features to make virtualization
+% and concurrency work. We have DSPs, GPUs, big.little, and Xeon
+% Phi. This is only scratching the surface. Second, we’re getting
+% tired of low-level languages and their associated security
+% disasters, we want to write new code, to whatever extent possible,
+% in safer, higher-level languages. Compilers are caught right in the
+% middle of these opposing trends: one of their main jobs is to help
+% bridge the large and growing gap between increasingly high-level
+% languages and increasingly wacky platforms. It’s effectively a
+% perpetual employment act for solid compiler hackers.
