“Bleeding edge” is an idiom used to describe new and risky developments, particularly in technology and the fine arts. It likely originated as a pun on “leading edge” and refers to the dangerous side of an edge. It can also be used for new medical treatments and styles in literature, music, and architecture.
The phrase “bleeding edge” is an idiom for any development that is new or cutting edge, but it also carries a high level of risk. First used in the 1980s, the saying has a lot in common with the similar idioms “leading edge” and “cutting edge”. While most commonly used in reference to new technologies, the saying can also be used for new styles in the fine arts.
Bleeding edge probably started out as a pun on “leading edge”. In aeronautics, the leading edge is a technical term for the airfoil or propeller blade at the front of the aircraft, which drives the aircraft’s motion. Metaphorically, the leading edge refers to the most recent development in a field. “Bleeding edge” comically alludes to an edge as a dangerous weapon.
Avant-garde also refers to a cutting-edge development, even if it doesn’t involve the same idea of risk as the avant-garde. The image is that of a knife, where the cutting edge is the useful side that guides each stroke. With the new phrase “bleeding edge,” the image is that of a bloody knife or sword, meaning the technology is useful, but dangerous.
Newly developed software in computers or telephones and newly built technologies, such as 3D movie projectors, are the most common developments referred to by the idiom. When 3D projectors first became available, the very fact that they were new caused problems. Theaters weren’t sure whether audience demand and the quantity of 3D-compatible movies would justify the original cost of installing the projectors, and producers didn’t know how many they would sell. The technology was impressive and new, but very risky.
Occasionally, “bleeding edge” can refer to the latest medical treatments, especially for life-threatening diseases. For mild illnesses, no one wants to use an unproven drug. While the treatments tested are unlikely to make someone well, most patients are willing to try whatever might help.
New styles in literature, music, visual arts, and even architecture are also sometimes referred to as avant-garde. With this kind of novelty, the risk lies in how audiences and critics react to the work. The similar slang term “edgy” is much more common for these innovations. For example, a solar-powered solar building in Dezhou, China was innovative in both architecture and energy efficiency when it opened in late 2009.
