美国当地时间5月5日凌晨，马斯克迎来了与歌手女友格莱姆斯的第一个孩子，也是马斯克的第六个孩子。
这个马斯克最小的儿子被取名为XÆA-12 Musk。此前，格莱姆斯解释过儿子名字的由来：其中X代表的是未知数，Æ，就是AI（爱或人工智能）的精灵语拼写。
这次采访中，马斯克也讲述了小儿子名字的来龙去脉。
马斯克称，这个名字大部分是女友想的，她在取名字方面很在行。在儿子的名字中，X的发音就像字母X一样，Æ的发音像ash，A-12部分则是自己的主意。之所以会用到A-12，是因为这是史上最酷的飞机SR-71侦察机的前身。
Elon Musk and Grimes reveal how to pronounce baby's name -- but they disagree
Elon Musk and Grimes have garnered plenty of attention since announcing the name of their newborn baby, but now it seems they can't agree on how it should be pronounced.
Speculation over the name X Æ A-12 has been a major topic of conversation since the couple welcomed the baby boy into the world on Monday, with questions over what the characters mean.
●speculation 猜测；推测，推断
Rumours that they are about to marry have been dismissed as pure speculation. 他们打算结婚的传言已证实只不过是猜测。
Speculation about his future plans is rife. 对他未来的计划猜测很多，众说纷纭。
The Canadian musician -- real name Claire Elise Boucher -- previously explained that Æ is the Elven spelling of AI, which is shorthand for artificial intelligence.
"It's just X, like the letter X. Then A.I. Like how you said the letter A then I," wrote Grimes on Thursday in response to a query on Instagram.
However, Musk told podcast host Joe Rogan a different pronunciation of the name in a conversation released Thursday, even as he credited Grimes for coming up with the moniker.

"First of all, my partner is the one that, actually, mostly, came up with the name," the Tesla and SpaceX CEO said. "Yeah, she's great at names."
Rogan then asked how to say it, to which Musk responded: "I mean it's just X, the letter X. And then, the Æ is, like, pronounced 'Ash'... and then, A-12, A-12 is my contribution."
This is the couple's first child together. Musk has five other children -- twins Griffin and Xavier and triplets Damian, Saxon and Kai -- from a previous marriage, and Rogan asked how it felt to have another child now.
The parents don't seem to agree on how to pronounce their baby's unusual name.
"Actually I think it's better being older and having a kid," said Musk. "I appreciate it more. Babies are awesome."
Unfortunately for the happy parents it seems their issues with X Æ A-12 go further than disagreements over pronunciation.
The unusual choice could fall foul of state rules in California, where the couple are based, which stipulate that names can only use the 26 alphabetical characters of the English language.
●stipulate 规定，约定；明确说明
She agreed to buy the car, but stipulated racing tyres and a turbo-powered engine. 她同意买这辆车，但指明要装赛车轮胎和涡轮动力引擎。

[ + question word ] We have signed a contract which stipulates when the project must be completed. 我们已签署合同，规定了项目必须完成的时间。
●alphabetical character 字母符号
For those curious about what the name means, Grimes broke down each character of the name in a post on Twitter.
She explained "X" stood for "the unknown variable," while Æ -- AI -- was shorthand for artificial intelligence and translates to "love" in several languages.
The 32-year-old star then shared that a part of her son's name is a reference to the couple's favorite aircraft.
"A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent," she added. Although Musk later corrected his partner, saying it was actually "SR-71."
Grimes concluded the explanatory post on Twitter by revealing that the "A" in the name also represents "Archangel," which she described as her favorite song.
