Last-Minute Halloween Costumes for the Tech-Obsessed

As Halloween approaches, TechCrunch has offered a timely and humorous guide for those in the technology sphere who find themselves without a costume. Published on October 30, 2026, the article provides a range of last-minute ideas, drawing inspiration from recent tech trends, industry personalities, and even cybersecurity scares, proving that even procrastination can yield a creative, tech-savvy outfit.

The suggestions blend insider tech jokes with readily available items, ensuring that even the most unprepared can find a fitting, culturally relevant ensemble for their Halloween festivities. From abstract AI concepts to recognizable figures like Mark Zuckerberg and Bryan Johnson, the list offers a playful nod to the year's most talked-about topics in tech.

Embracing Artificial Intelligence and Self-Improvement

One intriguing costume concept taps into the burgeoning discussion around artificial intelligence: “Recursive Self-Improvement.” Referencing fears expressed by AI leaders such as Dario Amodei and Sam Altman about AI's rapid, autonomous development, this costume shifts focus to personal betterment. It involves dressing as an idealized version of oneself, complete with props like a yoga mat, a large water bottle, and popular self-help books, symbolizing the perpetual quest for growth—whether human or algorithmic.

Another AI-inspired idea is the “Deceptively Cute AI Agent,” a nod to the charming yet powerful avatars launched by Meta and OpenAI. The costume emphasizes fluffiness and distinctive accessories like a hat or glasses to mimic the digital icons. The playful but eerie twist involves asking partygoers for “read/write access to their Gmail” throughout the night, highlighting the underlying privacy concerns associated with such agents.

Tech Personalities and Their Quirks

The article doesn't shy away from lampooning prominent tech figures. One suggestion is to dress as a “Guy who is actively recording you with Meta glasses,” playing on the controversy surrounding smart glasses and consent. The costume is simple: a pair of glasses with a large red or white circle attached to one lens, simulating a recording light, with a strict cautionary note not to actually record anyone.

Mark Zuckerberg's distinctive fashion sense also makes the list. The “Mark Zuckerberg wearing a vaguely unsettling T-shirt” costume involves donning an oversized, boxy black tee, ideally with a piece of paper declaring phrases like “Building is my love language.” For a more ominous effect, one could reference his Latin-emblazoned shirt, “Aut Zuck aut nihil” (“Either Zuck or nothing”), capturing his sometimes perplexing public image.

Digital Dilemmas and Biohacking

For those who find digital inconveniences genuinely terrifying, an “AI Usage Limit Notification” costume offers a relatable scare. This involves wearing cardboard signs displaying screenshots of notifications that signal a depleted token count for AI models like Claude, a particularly chilling prospect for “vibe-coders” dependent on these services.

Web security also gets a nod with the “PHP Vulnerability” costume, inspired by the recent “PHP-ocalypse” where AI unearthed critical flaws in the internet's foundational code. The costume asks for a T-shirt simply marked “PHP,” with the wearer committed to “the bit” by openly sharing their deep emotions and vulnerabilities throughout the night, drawing a parallel to the system's fragile state.

Finally, controversial biohacker Bryan Johnson earns two spots on the list. The first is simply “Bryan Johnson,” suggesting his recognizable image speaks for itself. The second, a “GLP-Bryan” couples costume, references his practice of using his body weight to calm a partner's nervous system. While peculiar and potentially awkward in a party setting, it requires minimal attire—just a T-shirt and jeans—making it a true last-minute option for the daring tech enthusiast.
