There&#x27;s also a huge amount of variance with underlying knowledge too. When you know something at a lower level and you want to work at a higher one, it&#x27;s easier to pick up.<p>Say you want to teach someone who only knows x86 assembly C vs someone who only knows Python. Both will have their struggles, but the person who knows how a CPU works already will have an easier go at grasping lower level features needed for most software development quickly.
