A succinct way I’ve framed the split is that a front-of-the-front-end developer determines the look and feel of a button, while a back-of-the-front-end developer determines what happens when that button is clicked.
Doing it right requires a different pace of working and a much broader thought process than “ok, let’s get this thing out the door.” Which is super tough because most workplaces place a huge emphasis on getting things out the door, and fast. Little agile tickets that are expected to be completed in micro sprints to me seem to be antithetical to doing it right.
Robert Smithson and other so-called land artists simply disengaged from architecture, placing their works in America's open landscape, leaving behind the museums and galleries Smithson referred to as "tombs". A new "expanded field" allowed artists to contextualize their work beyond the institutional frame of the museum or the commercial structure of a gallery. Richard Serra, who also began to move outdoors, at times chose to "attack" architecture, creating structures that disrupted or overwhelmed the buildings around them.
The artists of the Light and Space movement took another tack. Rather than fight or flee the architecture, they explored and manipulated it, approaching architecture as a kind of found object, creating a series of rooms that incorporated architecture and architectural structures directly into their art. Bruce Nauman summarized it well: "When you work in a gallery or museum, the architecture is a given. If you wanted to have a show, you didn't have a choice, except to deal with it. You had to find a way to either absorb architecture into the piece of build your own."
