■ CRITICAL RISK ■ Sports & Entertainment
For the calls themselves, yes — ball-tracking already out-judges humans and leagues keep expanding its authority. But umpiring is also game management, and sports are entertainment products that seem to want a human to boo, so the on-field role shrinks and hollows rather than vanishing overnight.

Our AI replacement risk score — how we score jobs
An umpire's job is split between judgment and governance. The judgment part is calling balls and strikes, outs, fouls, and boundaries in real time from imperfect vantage points. The governance part is running the game: managing pace, enforcing conduct rules, defusing arguments, ejecting the manager who's performing for the dugout, handling weather delays, and absorbing abuse from crowds as a professional duty. Minor-league and amateur umpires do all this for modest pay across long seasons of travel.
The judgment half is demonstrably a solved technical problem. Hawk-Eye and similar tracking systems call tennis lines with accuracy no human matches — several major tennis tours have removed line judges entirely. Baseball has tested automated ball-strike systems in the minors for years and is bringing challenge-based robot umpiring to the majors, where the strike zone becomes a measured volume instead of a negotiated opinion. Soccer's semi-automated offside, cricket's ball tracking, and VAR-style review layers all point one direction: the machine's call increasingly overrides or replaces the human's. Every expansion of these systems deletes a slice of what umpires were uniquely for — and deletes entire officiating positions, as tennis line judges discovered.
What remains human is the theater and the judgment calls that aren't measurements. Was that slide malicious? Is the pitcher throwing at batters? When do you eject someone, and when do you let the crowd have its pantomime argument? Leagues also move cautiously because officiating controversy is, perversely, part of the product. Amateur and youth sports can't afford tracking rigs, so weekend umpires outlast professionals. But the elite career path — the one with salaries — is being unbundled call by call, and 89 prices that in.
Automatability: our editorial assessment of current and near-term AI capability
Live now at the top of sport: tennis has removed line judges on major tours, automated ball-strike challenges are reaching top-flight baseball, and semi-automated officiating spreads through soccer and cricket this decade. Professional officiating crews shrink and their remaining duties tilt toward game management. Youth and amateur umpiring, priced below the cost of camera rigs, stays human indefinitely — but it was never the career; it was the pipeline.
The strike zone, effectively yes — automated ball-strike systems have graduated from minor-league trials to the challenge format at the top level, and the trajectory points toward machine authority over called pitches. The plate umpire remains for everything else: plays at the plate, check swings under review, game management, ejections. The job persists; its signature power is what's being taken.
Because their job was purely a measurement. A line call has no interpretive component — the ball is in or out — and Hawk-Eye measures it better, instantly, without sightline problems. Officials whose roles mix measurement with judgment and authority, like chair umpires and referees, survived. It's the cleanest demonstration of the pattern: automation removes the measurable calls first.
The traditional climb — years of minor-league grinding toward a big-league contract — is riskier because top leagues need fewer on-field decision-makers over time. Officiating as a paid avocation at amateur and college levels remains viable; there's a chronic shortage of youth-sport officials. Anyone pursuing the professional track should build parallel value in technology operation, evaluation, or league administration.
The human-management layer: reading when a confrontation is about to escalate, selling a close call with presence, judging intent behind a dangerous play, and keeping 22 adrenalized athletes inside the rules. Tracking systems produce measurements; they don't command respect or de-escalate a bench-clearing situation. Officials who excel at that layer become more valuable as the measurement layer goes automatic.
