Let's make this birthday one to remember.

78 years old (Born on July 21, 1946)

Happy Birthday, Brian! May your returns—like the economic theory you've brilliantly championed—continue to increase exponentially. Your groundbreaking insights into complexity have made economics a lot less predictable and infinitely more interesting; who knew chaos could be so enlightening?

From pioneering increasing returns to unraveling complexity theory's mysteries, you've shown us that life's greatest successes often emerge from embracing uncertainty. Here's hoping this birthday brings you joy as abundant as your contributions—and cake slices multiplying faster than economists can model them.

Cheers to another year of brilliant ideas and delightful unpredictability—you truly make complexity look easy!
