"The only intuitive interface is the nipple" (2012)

The quote "the only intuitive interface is the nipple; after that it's all learned" is commonly attributed to Bruce Ediger, though its true origins are unclear. Through archival research, the earliest known version appeared in January 1995 from Jay Vollmer, with Ediger using similar phrasings shortly thereafter and potentially refining it into the most widely recognized form by April 1995. The quote humorously critiques the overuse of "intuitive" to describe computer interfaces, suggesting that all human-computer interaction requires learned knowledge.
