“X is the set of all things” — This is the core theme, implying that the X platform (formerly Twitter) is evolving into a super-platform of “all-encompassing things,” integrating social, payment, AI, content, business, and other functions, becoming the central hub of digital life.

Illustration Explanation

The illustration includes three mathematical constants: e (the base of natural logarithm), i (the imaginary unit), π (pi), each given anthropomorphic dialogue bubbles, expressing:

e says: “JOIN ME AND WE'LL BE - ONE” — Suggesting fusion, unity, system integration, echoing the concept of “all-encompassing things.”

i says: “BE RATIONAL” — The imaginary unit i is non-real itself, yet calls for “rationality,” creating a philosophical contrast, possibly implying maintaining logic and order within complex systems.

π says: “GET REAL” — Pi is an irrational number, yet calls for “reality,” also creating philosophical tension, possibly symbolizing the transition from abstract theory to practical implementation.

A red circle surrounds π, emphasizing its “real” attribute, or hinting that in the “all-encompassing things,” the real world (physical + digital) is the core anchor.

Deeper Meaning

Through personification of mathematical symbols, Musk expresses his vision for the X platform:

e represents exponential growth and system integration;

i represents innovation and boundary-breaking;

π represents the real world and fundamental laws.

The combination of the three symbolizes that the X platform will integrate rationality, reality, and innovation, becoming the “ultimate platform” connecting everything.
