Taking things too literally seems to be a plague infecting many topics lately. I've interpreted the phrase similarly, do whatever you need to, just get "it" out of your head! Perfection is the enemy of good.
Hold on. I need to start a pointless semantics debate with you by taking what you said completely literally and it won't end until we've defined all the words.
How is the internet "tipping over" going to change what's fundamentally human?
Changing the interpretation of what someone said to fit your argument can be seen on the school playground and in Plato's Gorgias. It's not going away anytime soon.
Agreeing on an interpretation is the first step to conceiving an argument. Wrestling through this is a big part of having a discussion, and someone can always try to unfairly assume the interpretation that suits them, often the least charitable one.
I would be very, very careful about assuming that any observed behaviors are fundamentally human. Leave people alone to do their thing and you would get an entirely different set of behaviors. There's no question that the internet amplifies our worst tendencies, with a little help from the psychopaths on top of the big tech pyramid. It will tip over, because it's not viable in the long term.
This is a case where most people are going to naturally take it literally. Most people don't hear someone espouse "write drunk, edit sober" and think "oh i bet that's a metaphor, they hear a justification to drink more. This is actually the first time I've heard someone claim that quip isn't literal, ever. That's because its not formed as metaphorical advice, its formed as a very specific instruction. There's nothing there to indicate that it should be mulled over and tweaked apart for deeper information.
