It's not a software error though. The software worked exactly as it supposed to, pilots just didn't know about its existence and weren't trained.  
  
 Not saying it's going to hurt Boeing big times, but there is a difference between writing shitty code and lying about pilots not needing training on the new model.

Why change the people and spend more costs on educating them when you can just change the software
