"Quite a few people have to believe something is normal before it becomes normal - a sort of 'voting' situation. But once the threshold is reached, then everyone demands to do whatever it is"

In this quote, Alan Kay is highlighting the power of societal norms and how they are established. He recommends that in order for something to be thought about normal, a significant variety of individuals must believe in it. This can be seen as a kind of "voting" where the majority opinion dictates what is considered appropriate. However, when this threshold is reached and the bulk accepts it as typical, everybody begins to require it and it ends up being the new standard. This reveals the impact of group mindset and how it can form our beliefs and behaviors. It likewise stresses the significance of vital thinking and not blindly following societal norms.
