$PI What they wanted is exactly this effect. The Pi project team’s purpose: at first, to let everyone know that there is something called Pi; then to let everyone know what Pi is used for; later, to make everyone like this thing; later, to make everyone look forward to this thing; later, to make everyone remember this thing; and then later, to make everyone firmly and deeply remember this thing. Then, in the middle, to make everyone start disliking this thing; then to make everyone reject it; then to make everyone attack it. Later, to make everyone like this thing again; later, to make everyone deeply and firmly remember this thing. Finally, to completely reverse it and make everyone thoroughly remember this thing. Ultimately, the vast majority of ordinary people around the world can voluntarily, thoroughly, firmly, and naturally use this thing in a casual, effortless way. Finally, the Pi project team’s goal is achieved.
