When was the last time you pleaded ignorance? There are many times when it is better not to know everything because it is easier or more comfortable. The downside is that it could also kill you not to know. What do I mean by that? I am not talking about missing out on the juicy details. Technology makes it very possible to punch in a few simple responses to wizards or bots and viola, things just happen. The problem is when things break and you have no idea what just happened.
How much should you really know? I believe you should know "just enough to be dangerous." Einstein said "The only thing more dangerous than ignorance is arrogance." From time to time you just need to look under the hood and see what's going on.
