In some ways, you can almost see why trying to “erase” bad ideas is intoxicating, since humans seem endlessly drawn to them.
It’s like in tech circles, the joke goes that some Sci-Fi writer creates a horrible invention and includes a warning “DO NOT BUILD THE TORMENT NEXUS” and that warning, repeatedly, goes ignored. People are like “but we could make good profit from the Torment Nexus!”
AI is a good example. “If we don’t make the terrible AI, someone else will, so we have to make the Torment Nexus, errr, I mean AI.”
But trying to stop all these bad ideas is just Fahrenheit 451 with extra steps.
