When the biggest names in the artificial intelligence industry signed a voluntary safety pact alongside President Donald Trump last week, their signatures on the agreement made as much of a stir as their willingness to call AI “super intelligence” did.
On the left side of the signature page, near the midpoint, stood the rhythmic Sharpied peaks and zigzag of Trump’s name: the stylized, well-rehearsed autograph of a proud public performer. Over to the right, where the half-dozen tech leaders had signed on, things looked considerably more chaotic and peculiar.
The column began with Google’s Sundar Pichai, who set down a fluid stroke, embellished with two horizontal lines, two dots and a dash. It ended with Nvidia’s Jensen Huang signing his name with tall, swooping capital letters in a right slant.
The signatures in between were less elegant. Anthropic’s Dario Amodei and xAI’s Elon Musk scrawled their names in erratic cursive. Meta’s Mark Zuckerberg opened with a clumsy “m” and wobbled into an abstract finishing flourish. OpenAI president Greg Brockman, meanwhile, mustered a shaky, printed “gdb.”
The signatories had a collective net worth estimated at more than $1.5 trillion. What to make of the fact that men who aim to control the future appear to have the handwriting of middle school boys signing a classmate’s yearbook? What, if anything, does the seemingly awkward way they wield a pen suggest about the way they might wield their power and influence?
Some handwriting experts wondered whether a lack of panache in penmanship was generational.
Jessie Nucifora, co-president of the New York–based nonprofit Society of Scribes, pointed to the president’s distinctive sign-off as an example. Trump, at 80, is the oldest of all the signatories, followed by Huang, Musk and Pichai, in their 50s and 60s. Zuckerberg and Amodei are in their early 40s. Brockman, 38, is the youngest.

“If you look at Donald Trump’s signature, it’s very elaborate and intricate,” she said. “And then I feel like the younger they get, the less they’re caring.”
Kelli Fetter, owner and founder of the tutoring service Handwriting Solutions, wrote in an email that the tech leaders with the clumsier signatures “are possibly of the generation that never learned cursive, or at least not to the extent of achieving automaticity.”
“Without learning cursive, people aren’t sure how to sign their name,” Laura Ng, co-president of the Society of Scribes, added. “They just print it.”
Before the introduction of the typewriter in the late 20th century, handwriting was primarily a standardized business skill, rather than an avenue for personal expression, said Tamara Plakins Thornton, a historian and author of “Handwriting in America: A Cultural History.” Because contracts, bookkeeping ledgers and correspondences were written by hand, Thornton said people learned to write in uniform handwriting styles — the flowy, thick and thin strokes of roundhand; the graceful flourishes of Spencerian script; and the simplified Palmer Method, to name a few.
Signatures, meanwhile, were distinctive. In the medieval and early modern eras, they were more akin to sophisticated monograms, one retired medieval literature professor, who asked not to be named in the story, wrote in an email. Writers would deliberately distort certain letters to convey their identities to close confidantes and obscure them from others.
Some modern signatures still bear these qualities, he added.
“The president’s famous scrawl is an obvious example, as are Pichai’s, Zuckerberg’s, and Huang’s signatures, reduced to excerpted pen strokes deliberately fused together,” he wrote. “All of them show signs of formal practice to reproduce a stamp-like image.” Zuckerberg’s, he wrote, “actually ends with what might pass for an early modern Secretary Hand pen flourish of the sort used to make counterfeiting more difficult.”

Pichai’s signature followed a format common in Europe, Ng said, with a first and last initial, a squiggle for the last name and an underline.
For much of history, only notable figures were expected to have stylized signatures, Thornton said. Napoleon Bonaparte signed his name with strong, angular lines and dramatic flourishes. And John Hancock’s grand, ornate signature on the Declaration of Independence became so famous that his name is now a term for signatures in general.
By the 1800s, Thornton said, the public had grown fascinated with the signatures of notable men and women. Publishers sold albums of facsimile autographs, and the interest developed into the field of graphology, the practice of analyzing a person’s handwriting to purportedly discern personality traits. In the late 1800s and the 1900s, as the forces of conformity and anonymity bore down on urban life, Thornton said everyday people began adding flair to their own signatures, too.
Most of the tech leaders do not seem to be trying to impress anyone with their style. In the literature professor’s estimation, “Brockman’s lower-case initials are a modest compromise between bare legibility and obscurity,” while “Amodei and Musk reproduce a kind of approximation of their names’ characters in script that appears fatigued and careless.”
Brockman, Amodei and Musk’s signatures, he added, resembled those he saw among high schoolers in the ’60s — “usually a sign that they were tired and had little respect for the document they were signing.”
Beyond aesthetics, is there anything to be gleaned from Huang’s large, looping capitals or from Brockman’s wobbly lowercase initials? Psychologists and handwriting historians alike are skeptical of the field of graphology, but those who specialize in the discipline did offer some thoughts.
Emma Bache, a UK-based graphologist, said that Brockman’s hesitant strokes indicated impulsiveness, while Sheila Lowe, president of the American Handwriting Analysis Foundation, wrote in her organization’s newsletter that it signals “he is quick to get to the bottom line, cutting away all the non-essentials.”

Meanwhile, Bache said the lower zone loops of Huang’s signature indicate that “he could be quite charismatic on the outside, but quite ruthless inside,” while Lowe said it signaled “a strong attachment to the past, as well as a desire to include as many associates and friends as possible in his vast number of activities.” Zuckerberg’s loops, meanwhile, reflect a sense of childlike confidence, according to Bache, and a need to push forward, according to Lowe.
The disproportionally tall capitals in Musk’s signature, Lowe wrote, are the sign of “an emotionally underdeveloped writer who has a great deal of pride in his achievements.” Bache said the large letters convey creative and forward thinking.
And Amodei, according to Bache, is an overthinker and a worrier, while Pichai is a highly intelligent strategist.
Signatures aside, the AI safety accord raised plenty of other questions — about the lack of accountability and the integrity of the document itself. The pact was not signed in public, and its low-resolution format made it difficult to ascertain whether the document was signed in ink or electronically or whether existing digital signatures were merely affixed to the document, said Jennifer Naso, a forensic document examiner.
The document also does not include a date or any official government insignia that would establish a relationship between page one and page two, she said. “This is an official White House document and agreement. You would expect to have the letterhead,” she said. “This looks like someone just typed it out on Word and printed it from their own computer.”
The signatures of these AI leaders might not reveal much about their intentions or their motivations. But the glaring typographical error under Trump’s name that labeled him President of the “Unites States” is plenty illuminating, the retired professor wrote.
“In the end, the fact that all of them signed a document they had presumably held in their hands at arm’s length but had not read closely enough to distinguish ‘Unites’ from ‘United’ says a lot more about the whole thing,” he concluded.

上周,人工智能行业的巨头们与唐纳德·特朗普总统签署了一项自愿安全协议,他们的签名和他们愿意将人工智能称为“超级智能”一样,都引起了轰动。
在签名页左侧,靠近中间位置,是特朗普名字那富有节奏感的马克笔勾勒出的尖峰和锯齿状线条:这是位骄傲的公众人物精心排练的、风格化的签名。而在右侧,六位科技领袖的签名处,看起来则混乱而怪异得多。
专栏以谷歌的桑达尔·皮查伊(Sundar Pichai)的签名开篇,他笔画流畅,点缀着两条横线、两个点和一条短横线。专栏以英伟达的黄仁勋(Jensen Huang)的签名结尾,他用高挑流畅的大写字母向右倾斜地签名。
中间那些签名就没那么优雅了。Anthropic 的 Dario Amodei 和 xAI 的 Elon Musk 都用潦草的草书写下了自己的名字。Meta 的 Mark Zuckerberg 开头笨拙地写了个“m”,最后勉强用抽象的笔画收尾。而 OpenAI 的总裁 Greg Brockman 则勉强签了一个颤抖的印刷体“gdb”。
这些签署者的净资产总额估计超过1.5万亿美元。这些意图掌控未来的人,他们的笔迹却像是初中生在同学的毕业纪念册上签名一样,这该如何解释?他们看似笨拙的用笔方式,又暗示着他们运用权力和影响力的方式吗?
一些笔迹专家想知道,缺乏优美的笔迹是否是代际差异造成的。
纽约非营利组织“书信社”(Society of Scribes)的联合主席杰西·努西福拉(Jessie Nucifora)指出,总统独特的签名就是一个例子。80岁的特朗普是所有签名者中最年长的,其次是黄仁勋、马斯克和皮查伊,他们都在50到60岁之间。扎克伯格和阿莫迪都40岁出头。38岁的布罗克曼是最年轻的。

“如果你仔细看看唐纳德·特朗普的签名,你会发现它非常精致复杂,”她说。“而且我觉得,年轻人越年轻,就越不在乎这些。”
手写辅导服务机构 Handwriting Solutions 的所有者兼创始人 Kelli Fetter 在一封电子邮件中写道,签名比较笨拙的科技领袖“可能是从未学过草书的那一代人,或者至少没有达到能够熟练书写的程度”。
“如果不学习草书,人们就不知道该如何签名,”书吏协会联合主席劳拉·吴补充道,“他们只会用印刷体签名。”
历史学家、著有《美国手写:一部文化史》一书的塔玛拉·普拉金斯·桑顿指出,在20世纪后期打字机问世之前,手写主要是一种标准化的商业技能,而非个人表达的途径。由于合同、账簿和信函都是手写的,桑顿表示,人们学会了使用统一的手写风格——例如,圆体字流畅的粗细笔画;斯宾塞体优美的装饰性笔画;以及简化的帕尔默体等等。
与此同时,签名也各具特色。一位不愿透露姓名的退休中世纪文学教授在邮件中写道,在中世纪和近代早期,签名更像是精致的字母组合图案。作家们会故意改变某些字母,以便向亲近的知己表明身份,同时对其他人隐瞒身份。
他还补充说,一些现代签名仍然具有这些特点。
他写道:“总统著名的潦草签名就是一个明显的例子,皮查伊、扎克伯格和黄的签名也是如此,它们都被简化成刻意拼凑在一起的笔画。所有这些都显示出一种正式的练习痕迹,旨在复制类似印章的图像。”他还写道,扎克伯格的签名“实际上以类似早期现代秘书手写体的一种笔画结尾,这种笔画是为了增加伪造的难度。”

吴先生说,皮查伊的签名遵循欧洲常见的格式,包括名字和姓氏的首字母,姓氏用波浪线表示,并加一条下划线。
桑顿说,在历史的大部分时期,只有杰出人物才需要使用风格化的签名。拿破仑·波拿巴的签名线条硬朗有力,笔画华丽醒目。而约翰·汉考克在《独立宣言》上那气势恢宏、装饰华丽的签名更是闻名遐迩,以至于他的名字如今成了签名的代名词。
桑顿说,到了19世纪,公众对名人的签名越来越感兴趣。出版商出售签名复制册,这种兴趣逐渐发展成为笔迹学——一种分析笔迹以推断性格特征的学科。桑顿说,在19世纪末和20世纪初,随着循规蹈矩和匿名化的趋势席卷都市生活,普通人也开始在自己的签名上增添一些个性化的元素。
大多数科技领袖似乎并不刻意用个人风格来给人留下深刻印象。这位文学教授认为,“布罗克曼的小写首字母是介于清晰易读和晦涩难懂之间的一种适度折衷方案”,而“阿莫迪和马斯克则用手写体近似地模仿了他们名字的字母,显得疲惫而随意”。
他补充说,布罗克曼、阿莫迪和马斯克的签名与他在 60 年代高中生身上看到的签名很像——“这通常表明他们很累,对他们签署的文件缺乏尊重”。
抛开美学因素,我们能否从黄氏笔画大而流畅的大写字母或布罗克曼笔画歪歪扭扭的小写字母中解读出什么信息?心理学家和笔迹史学家都对笔迹学领域持怀疑态度,但该领域的专家确实提出了一些见解。
英国笔迹学家艾玛·巴赫表示,布罗克曼犹豫的笔画表明他性格冲动;而美国笔迹分析基金会主席希拉·洛在其组织的通讯中写道,这表明“他能迅速抓住重点,剔除所有不必要的东西”。

与此同时,巴切表示,黄的签名中下部的环形图案表明“他外表魅力十足,内心却冷酷无情”,而洛则认为这表明“他对过去有着强烈的依恋,并且渴望尽可能多地将同事和朋友纳入他丰富多彩的活动中”。巴切认为,扎克伯格的环形图案则反映了一种孩童般的自信,而洛则认为,这体现了他不断进取的精神。
洛伊写道,马斯克签名中不成比例的高大字母表明“他是一位情感不成熟、对自己的成就极度自豪的写作者”。巴切则表示,大写字母传达了创造力和前瞻性思维。
巴切认为,阿莫迪是个爱想太多、爱操心的人,而皮查伊则是一位非常聪明的战略家。
撇开签名不谈,这份人工智能安全协议还引发了许多其他问题——例如缺乏问责机制以及文件本身的完整性。文件鉴定专家詹妮弗·纳索表示,该协议并未公开签署,而且其低分辨率格式使得人们难以确定文件是手写签名还是电子签名,或者是否只是简单地将现有的数字签名附加到文件上。
她还说,这份文件既没有日期,也没有任何官方政府标识,无法证明第一页和第二页之间的关联。“这是一份白宫的正式文件和协议,理应有信头,”她说,“这看起来像是有人用Word打出来,然后从自己的电脑上打印出来的。”
这些人工智能领导者的签名或许无法揭示太多关于他们的意图或动机的信息。但这位退休教授写道,特朗普名字下方那个明显的拼写错误——把他写成了“美利坚合众国”总统——却足以说明问题。
“最终,他们都签署了一份文件,而这份文件他们可能只是拿在手里,并没有仔细阅读,以至于无法区分‘Unites’和‘United’,这更能说明整件事的问题,”他总结道。
