Just 60 of the Fortune 500 of 1955 remain in the hallowed group. The rest (like American Motors, above, subsumed by Chrysler in 1987) have been largely the victims of changing times, tough competition or their own missteps.

What's happening: Tom Siebel, founder of C3.ai, an artificial intelligence firm that serves big corporations and the Army, says that this is an existential moment for current Fortune 500 companies that don't move quickly to adapt to the new age of AI and robotics.

"We are in a mass extinction event," says Siebel, who stopped by the office last week to talk about his new book, "Digital Transformation."

Westinghouse, Sears, and Toys "R" Us are among the slain former giants, Siebel notes. "You have companies with new DNA filling the voids in the ecosystem. You have Amazon rolling everyone. If you are Walmart, you are looking down that barrel of a gun. You are in a world of hurt," he said.

Siebel is describing one of the current megatrends:

  • Last month, we reported that the day of the conglomerate is over: From globe-spanning companies, they are being forced by political and economic circumstance into regional operations.
  • The FT's Rana Faroohar says companies are adapting to "the age of deglobalization."

"It's either you're on the train or you're on the track," says Siebel.

Hiroshima mayor warns of rise of nationalism on 75th anniversary

Hiroshima's Mayor Kazumi Matsui on Thursday urged the international community to work together to defeat the coronavirus pandemic and warned against an increase in "self-centered nationalism," per the Washington Post.

Why it matters: He said at a remembrance service on the atomic bombing of the Japanese city that the 1918 flu pandemic killed millions as countries fighting in World War I were unable to overcome the threat together, per DPR. "A subsequent upsurge in nationalism led to World War II," he added. The U.S. bombing of Hiroshima on Aug. 6, 1945 and Nagasaki three days later contributed to the end of World War II, but tens of thousands of people died. At the service, Prime Minister Shinzo Abe lamented nuclear weapons' "inhumanity," but he didn't mention Japan's wartime past, WashPost noted.

LeBron James on Trump NBA protest remarks: "We could care less"

LeBron James responded on Wednesday night to President Trump's comments calling NBA players "disgraceful" for kneeling during the national anthem to protest racism and that he won't watch games because of the action.

The big picture: Trump has repeatedly criticized sports players for taking the knee since 2016. But James said during a news conference, "I really don’t think the basketball community are sad about losing his viewership, him viewing the game." November's elections marked "a big moment for us as Americans," he said. "If we continue to talk about, 'We want better, we want change,' we have an opportunity to do that," he added. NBA Commissioner Adam Silver has said the league will "respect peaceful protest."
