@exoteric: Rob Pike is one of my favorite tech personalities. Here's what Miguel de Icaza (who is currently holding the dotnet torch) have to say about him:

 Rob Pike's talk on Concurrency is not Parallelism. Rob is one of the crisper minds in software development, anything he writes, you must read, everything he says, you must listen to. (ref)

About that concurrency slide deck, you know waht's more amazing? Watch this deck: http://talks.golang.org/2012/go-docs.slide , It gets really amazing after slide 20 or so. [spoiler: they created a text based slide language]

 

One more thing: Rob Pike is one of the creators of the coolest new systems language, and he knows his way around HTML and friends.
