  Another example for all you computer folks out there: ultimately, all software
  engineering is just moving electrons around. But imagine how hard your job would
  be if you could only talk about electrons moving around. No arrays, stacks,
  nodes, graphs, algorithms—just those lil negatively charged bois and their 
  comings and goings.

I think this too easily skips over the fact that the abstractions are based on a knowledge of how things actually work - known with certainty. Nobody in CS is approaching the computer as an entirely black box and making up how they think or hope it works. When people don't know how the computer actually works, their code is wrong - they get bugs and vulnerabilities they don't understand and can't explain.
