I get that people here don't like profanity, but I don't see any slight in describing engineering decisions like optimizing for common workloads today over hypothetical loads tomorrow as 'fucking over the future'. Slightly hyperbolic, sure, but it's one of the most common decisions made in designing systems, and commonly causes lots of issues down the line. I don't see where saying something is a mistake that looks obvious in retrospect is a slight. Most things look obvious in tetrospect.
