Scar Tissues Make Relationships Wear Out

04/26/2013. From a lecture by Professor John Ousterhout at Stanford, class CS142. This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it’s hard both for personal relationships and for business relationships. And to me, it’s pretty amazing that two people can stay married for 25 years without killing each other.
