Has there ever been an instance in history when this strategy worked? Plato argued that writing things down will make your memory worse, and less skilled as a debater (kind of true!) How are the Luddites doing at textiles? I remember the arguments that using 'high level languages' like C and Pascal will make you not understand machine specific details (kind of true!)

I respect that you want to learn how things are done, that is a great trait. But once you learn how its done, you should use the tools to free up cognitive load for more difficult tasks.

Preparing for the zombie apocalypse seems silly to outsiders, but when it actually happens, who's gonna be laughing?
