An amazing talk that really taught me some deeper and more true principles in computing. https://www.youtube.com/watch?v=rHIkrotSwcc "There are no zero cost abstractions."

@cnlohr What a great talk, I was genuinely shocked when I saw unique_ptr has runtime cost. You really know nothing until you measure it.
@doragasu It really does blow my mind how sneaky some of these things are. And why microbenchmarks can't prove the lack of costs.
