The long run keeps getting shorter
In the long run, we're all dead, sure that's still true.
But the other long run effects--in the long run, you get caught, in the long run, kindness wins out, in the long run, we learn about who you really are--all of those are happening faster than they used to.
The short run has always been short (and it's getting shorter still). The real change, though, is how short the long run is getting.
