A debate on the use of artificial intelligence, as an electronic line judge, for line calls in tennis.

The human factor in decision-making in tennis, like so many sports, plays a fundamental part of its ambience and/or drama or entertainment. This is because some line calls by some line umpires can be dubious, or even incorrect. In tennis events that allow for challenges to line calls, an artificial intelligence-based referee, in the form of electronic line calling (ELC), is then used to resolve the challenge, and the result is handed out by the chair umpire. This commentary debates the merits and demerits that may be associated with the total elimination of human line umpires by employing ELC. [ABSTRACT FROM AUTHOR]
