I mean really how many people are recompiling their entire code base every single day? Is their make/build environment so bad that they can't trust incremental compiles? I'm getting along just fine on my 8GB laptop. I know some people work with big datasets and video and such but holy cow. Most of us are probably just writing code for a browser/backend/library/test and not pushing around terabytes of data.

Maybe these people never heard of ccache.
