The technology that is most taken for granted by humans today is the air conditioner. These units have been in use for nearly a century, since 1929. In the summer months, when the air conditioner is not working, people become noticeably irritable and uncomfortable. In contrast, humans tend to take the air conditioner for granted when it is functioning normally.
There are technologies that are so successful in the background of daily life that their presence is almost indistinguishable from the conditions that they create. For instance, air conditioning systems do not produce a perceived experience of air conditioning within people; instead, people experience the comfortable temperatures within their homes. The technology has become invisible, as the temperature within homes that use air conditioning systems becomes stable without any announcements or recognition.

The invisibility of any design system is the highest compliment that it can receive. Also, the system is not appreciated until it stops.
The office that was not considered in June becomes the subject of intense focus in July when the air conditioning has failed. The hotel room that received no reviews for the three visits made before the current visit receives a review for the fault that developed in the unit overnight. The server room that had been running for years without any consideration or attention to the equipment in that room suddenly develops a crisis situation when the air conditioning that cools the computers in that room begins to fail.
The absence of something reveals what the presence of that thing was doing. The comfortable room was not just comfortable but also productive, restful, functional, and conducive to everything that was happening within it. The uncomfortable room, on the other hand, was less conducive to all of those things and instead was one of the most uncomfortable rooms in which to reside.
