Cars going faster than humans or horses isn't very interesting these days, but it was 100+ years ago when cars were first coming on the scene.
We are at that point now with AI, so a more fitting headline analogy would be "In a world first, automobile finishes with gold-winning time in horse race".
Headlines like those were a sign that cars would eventually replace horses in most use-cases, so the fact that we could be in the the same place now with AI and humans is a big deal.
It was more than interesting 100+ years ago -- it was the subject of wildly inconsistent, often fear-based (or incumbent-industry-based) regulation.
A vetoed 1896 Pennsylvania law would have required drivers who encountered livestock to "disassemble the automobile" and "conceal the various components out of sight, behind nearby bushes until [the] equestrian or livestock is sufficiently pacified". The Locomotive on Highways Act of 1865 required early motorized vehicles to be preceded by a person on foot waving a red flag or carrying a red lantern and blowing a horn.
It might not quite look like that today, but wild-eyed, fear-based regulation as AI use grows is a real possibility. And at least some of it will likely seem just as silly in hindsight.
