Unlike many execs who avoid the spotlight during crisis, Zuckerberg has faced grilling by U.S. Congress, the EU Parliament, and more — essentially becoming the public face of digital regulation and privacy reform worldwide.

Through the Chan Zuckerberg Initiative, Zuckerberg quietly funded and helped design “Summit Learning,” a personalized learning platform now used in hundreds of U.S. schools — blending tech and education reform in a way most CEOs never attempt.

While others made loud promises, Zuckerberg invested silently in one of the world’s largest AI compute clusters — making Meta a serious contender in AI, with open-source models (like LLaMA) quietly changing the game for researchers.

Zuckerberg is red-green colorblind, which influenced Facebook's blue color scheme, as blue is the color he perceives best.

He learned Mandarin to communicate with his wife's family and has conducted interviews in the language.

Known for his love of barbecuing, he once hosted a Facebook Live session discussing his passion for smoking meats.
