Ben Grosser’s solo exhibition “Software for Less” opens at Aksioma, Lubljana, as the final chapter of a four-part program on “New Extractivism.” The American artist and programmer whose works examine how clicks, likes, and endless notifications fuel our “appetite for more” presents several recent software provocations that “produce less profit, less data, and fewer users.” Case in point: Minus (2021), a social network that limits users to 100 posts—for life.
