A few days ago came the astonishing news that the world record in the half-marathon was obliterated by a 5-foot-5 humanoid robot named Lightning in Beijing.

Now a robot named Ace has achieved another milestone for AI and robotics by defeating expert-level humans at table tennis in Tokyo, according to a study published Wednesday in the scientific journal Nature.

What’s next, a robotic baseball player named Babe that swats 500-foot home runs and throws 120 mph pitches, eclipsing Shohei Ohtani’s real-life achievements and commanding a billion dollar contract?

It’s all fun and games until it isn’t.

Extraordinary athletic achievements by AI robots might seem innocuous, especially compared to far more grave threats described by various experts, including the landmark publication “An Overview of Catastrophic AI Risks” by the Center for AI Safety in 2023.

To name a few: Misinformation and social media manipulation; job displacement and economic inequality; cybersecurity threats; lethal autonomous weapons; environmental impact; psychological dependence; and ultimately, the existential risk to humanity of losing control of rogue AI systems.

For now, let’s get back to ping-pong.

Ace was developed by good, old Sony, the 80-year-old makers of gaming consoles, televisions, smartphones, cameras and audio equipment that we enjoy every day.

Of course Sony has an AI research division, and while most consumers were still going ga-ga over PlayStation 5 Pro 2TB, it developed the first robot to attain expert-level performance in a competitive physical sport that requires rapid decisions and precision execution.

Ace integrates nine synchronized cameras and three vision systems to track the spinning plastic ping-pong ball. Its lightning-fast processing time would be the envy of even Lightning, the humanoid robot that broke the world record in the half-marathon by nearly seven minutes.

“Here we present Ace, to our knowledge the first real-world autonomous system competitive with elite human table tennis players,” the study said. “Ace addresses the challenges of physical real-time interaction through a new, high-speed perception system using event-based vision sensors and a new control system based on model-free reinforcement learning, as well as state-of-the-art high-speed robot hardware.”

Ace showed out in matches that followed International Table Tennis Federation rules and were officiated by licensed umpires. Most of the matches took place in 2025 — before table tennis tale “Marty Supreme” even hit theaters — although Ace defeated professional players as recently as March.

One such human is Mayuka Taira, who said in comments provided by Sony AI to Reuters that the robot’s strengths are what one might expect: unpredictability and an absence of emotion.

“Because you can’t read its reactions, it’s impossible to sense what kind of shots it dislikes or struggles with, and that makes it even more difficult to play against,” Taira said.

Initial real-world applications of Ace-like robots likely would be in manufacturing and service industries, although untapped potential lies across sports, entertainment and safety-critical environments, according to the study.

“These results highlight the potential of physical AI agents to perform complex, real-time interactive tasks, suggesting broader applications in domains requiring fast, precise human–robot interaction,” the study said.

Those domains certainly could include baseball diamonds, basketball courts and gridirons. Hockey rinks could be lumped in provided robots can skate.

AI already is used in MLB. The vaunted Automated Ball-Strike system (ABS) uses AI-powered Hawk-Eye camera technology and computer vision to determine if pitches are strikes or balls. Twelve high-speed cameras track ball flight and AI delivers the definitive call to the scoreboard within seconds of a challenge.

A robotic batter facing a robotic pitcher with calls made by ABS might eliminate any disagreements over balls and strikes.

Terrifying.

The Dodgers are too good, and too rich. If the owners of other major league teams ultimately deem that combination so objectionable that they shut down the sport this winter because of it, they will risk a rupture in one of the greatest fan bases in American sports history.

The four million tickets the Dodgers sold last season tells one part of the story. Here is an arguably better one: For decades, the Dodgers and Lakers have dominated Los Angeles sports and left every other team far behind in popularity.

For now, after back-to-back World Series championships, the Dodgers have left even the Lakers far behind in popularity, and every other team in town even further behind.

In a Loyola Marymount survey asking Los Angeles County residents to identify their favorite among the 12 pro sports teams within the local media market, nearly half picked the Dodgers.

The Dodgers’ lead over the Lakers — 43% to 28% — represented the largest gap between the teams in the nine editions of the survey, first conducted in 2014 by the Thomas and Dorothy Leavey Center for the Study of Los Angeles.

The Rams ranked third, at 7%, followed by the Kings at 5% and the Angels at 4%.

The two women’s teams — Angel City FC and the Sparks — tied for last, each with less than 1% of the vote. Even when the study separated votes by gender, the two women’s teams got less than 1% of the vote from women.

As recently as 2018, five teams beyond the Dodgers and Lakers — the Angels, Clippers, Galaxy, Kings and Rams — attracted at least 4% of the vote. In this year’s survey, only the Rams did.

“I’m a big Rams fan,” said Fernando Guerra, the center’s director, “and I still put the Dodgers first.

“I love all these teams. But, when you have to choose one, it’s the Dodgers.”

Dodgers president Stan Kasten pointed to the popularity and excellence of the players, the cherished ballpark and the generational fan support as factors contributing to the top ranking.

“If you have a lot of good elements but you don’t win, you’re not going to be as high,” Kasten said. “And, if you win but you don’t have the other elements, you’re not going to be as high.

“I think, right now, we’re as close as you can be to clicking on all cylinders.”

Beyond the winning, Guerra cited Shohei Ohtani as a driving force behind the Dodgers’ popularity, and not just as a tourist attraction, merchandise driver, and the foremost product endorser in sports.

In 2018, Ohtani’s debut season with the Angels, 8% of fans that identified themselves as Asian picked the Angels as their favorite team and 34% picked the Dodgers — a terrific showing for the Angels, since the study polls residents in L.A. County, not Orange County.

That demographic this year: 4% picked the Angels, 47% picked the Dodgers.

In their 10 years since returning to Los Angeles, the Rams have made seven playoff appearances and two Super Bowl appearances, winning one. All that, and a half-century in their previous run in L.A., and their membership in the most popular sports league in America, and the best they could do was 7%.

“It’s just tough to break the Lakers’ and Dodgers’ hold,” Guerra said. “It’s not like we don’t love the Rams or the others. It’s just not your top priority.”

The Lakers and Dodgers have combined to win 20 championships in Los Angeles. The other 10 teams that call this market home have combined to win 16.

In the 13 seasons since Mark Walter and Co. bought the Dodgers, the team has won 12 division titles, made five World Series appearances, and won three championships. In the same time, the Lakers have won three division titles, advanced past the first round of the playoffs twice, and won one championship.

Walter bought a controlling interest in the Lakers last year. He has installed Lon Rosen, formerly the Dodgers’ executive vice president and chief marketing officer, as the Lakers’ president of business operations.

“When the Lakers are winning a lot of championships, they’re No. 1,” Rosen said. “When the Dodgers are, they’re No. 1.

“It’s a good position to be in, since we control both teams, and both teams are highly successful.”

In this moment, the Dodgers are highly successful.

“The Lakers and Dodgers are going to be neck and neck very soon,” Rosen said. “The Lakers will 100% be champions again soon.”

The Dodgers do not concede the days of neck and neck will return. Kasten, remember, said the Dodgers were as close as they could be to clicking on all cylinders.

“We don’t take that for granted,” he said. “We know we can do even better.”
