It has been five days since a dozen boys were rescued from a flooded cave in Thailand, and five days since Elon Musk has been wandering in a Twitter labyrinth of his own making.
The Silicon Valley engineer and billionaire was briefly seen in Thailand last week, hauling a miniature submarine to the mouth of the cave just before an international dive team rescued the boys without it.
Since then, he has been arguing with people who accuse him of shoehorning himself into the drama and imagining hypotheticals in which rescuers had not deemed his hastily built submarine unnecessary and impractical.

This has, inevitably, led Musk into public arguments people who actually participated in the rescue operation - a rhetorical war that he drastically escalated on Sunday, when he called one of the cave explorers a "pedo," prompting the explorer to consider a lawsuit.
Musk - briefly - is a person who co-founded the e-commerce site PayPal, who later built rocket ships through SpaceX and electric cars through Tesla, and who is alternately hailed as a visionary or derided as a showboater for pitching ideas to begin colonizing Mars next decade, or build highways under Los Angeles, or create a website to rate the credibility of journalists who report on problems at his electric-car company.
The cave saga, on the other hand, was a massive, weeks-long operation to rescue a boys soccer team from a flooded tunnel system, an effort led by the Thai government, carried out with the help of British divers, and watched obsessively by much of the world.
It really had nothing to do with Musk - until one of his Twitter fans suggested, a week and a half into the operation, that he build an invention to help get the boys out.
As Abby Ohlheiser has already chronicled for The Washington Post, Musk accepted the challenge with "a lengthy, live brainstorming process on Twitter," which ended when he traveled to Thailand with a miniature submarine made from rocket parts, tweeted some photos of the cave, left the device there and went home.
Hours later, a dive team sans submarine began extracting the children - ultimately successfully. And while Musk's fans lauded his intentions, his submarine drive-by also became the butt of many jokes.
The mockery was fueled, in part, by reports that top rescue officials had considered Musk's submarine impractical for the cave's tight-winding passages.
As Ohlheiser wrote, Musk soon "started a Twitter argument over how much credit he deserved for offering to help save the youths," during which argument he showed off an email of himself corresponding with one of the British divers and incidentally claimed that the Thai official in charge of the rescue had not been in charge.
Then, three days after the rescue operation was completed, CNN posted an interview with a British spelunker who had helped locate the boys. That spelunker, Vernon Unsworth, called Musk's submarine "a PR stunt."
"He can stick his submarine where it hurts," Unsworth told CNN. "It just had absolutely no chance of working. He had no conception of what the cave passage was like."
Like other critics, Unsworth noted that the flooded tunnel was extremely narrow and twisted. "The submarine, I believe was about five, six feet long. Rigid," he said. "So it wouldn't have gone around corners or around any obstacles. It wouldn't have made it the first 50 meters."
Unsworth concluded this portion of the interview by claiming that Musk had been quickly asked to leave the cave during his much-tweeted-about visit.
The interview spread through the weekend - until a Twitter user baited Musk into responding to it, just as he had been lured by another fan into devising his submarine.
In a series of tweets that Musk appears to have deleted while this article was being written, he claimed that he had been repeatedly asked by rescuers to build the sub. He wrote that he was escorted into the cave by Thai Navy SEALS - "total opposite of wanting us to leave."
He said he had not seen Unsworth - whom he dismissed as "this British expat guy who lives in Thailand" - during his brief guided tour of the cave system and suggested that, therefore, Unsworth had not actually participated in the rescue operation. (Unsworth absolutely and crucially had, per CNN.)
Furthermore, Musk insisted that his submarine (designed in consultation with "cave experts on the Internet," he wrote) would have worked. He bragged that he would one day pilot it through the now child-free cave system as proof.
And midway through his rant, for some inexplicable reason, he accused Unsworth of sex crimes.
"Sorry pedo guy, you really did ask for it," Musk wrote, clarifying in a follow-up tweet that he meant "the Brit expat diver" was a pedophile.
Generally confused, some Twitter followers guessed that Musk was dubiously linking Unsworth (who has been mapping the Tham Luang caves for a decade) with Thailand's epidemic of child-sex tourism.
"Bet ya a signed dollar it's true," Musk wrote late Sunday morning, a few hours before he deleted his tweets - too late to avoid yet another deluge of public criticism.
Condemnation of his remarks seemed universal - a mixture of outrage at the slur against Unsworth, outrage against the implied slur against Thailand, and yet more mockery of Musk.
The Guardian, a British newspaper, consulted a legal expert who thought Unsworth had "a cast iron case of libel." The spelunker did not necessarily disagree when reporters asked for his reaction to the pedophile comments.
"I'll take advice when I get back to London," he told 9 News during a celebratory ceremony outside the evacuated gave.
"Legal?" the reporter asked.
The accusation had angered and astonished him, Unsworth told the Guardian. He said Musk, whom he had never met, must have a "bruised ego." And speaking to a gaggle of TV reporters at the ceremony, Unsworth explained:
"I believe he's called me a pedophile. Well." He cleared his throat. "By definition, I mean rescuing 12 young boys, by definition that puts everybody else in the same context."
"I'm not going to make any further comment about him," Unsworth continued. "But I think people realize what sort of guy he is."
"Would you consider taking legal action against him?" a reporter asked, again.
"Yes," Unsworth said instantly. "Yes, it's not finished."
Spokespeople at Musk's companies, Tesla and SpaceX, have not replied to requests for comment on his tweets or the possibility of a libel lawsuit.
James Anderson, one of the largest shareholders in Tesla, told the Guardian that he planned to convey his concerns to the company.
