I have been watching alot of videos about computer building, and in every one of them there is always that volatile step of putting the CPU in. 

Either the CPU has pins that break easily, or the CPU socket has pins that break easily depending on the brand. 

"WHY DOES IT HAVE TO BE PINS" // a violent thought by me..

Why not only have little square contact surfaces or even better, half sphearical dents on the CPU and little depressions in the socket.
