  • Buffett has warned about the enormous threat posed by Oppenheimer's creation, the atomic bomb.

Millions of people are buzzing to see "Barbie" and "Oppenheimer" this weekend — a cinematic showdown and pop-culture phenomenon dubbed "Barbenheimer" by some. Warren Buffett has nodded to both the iconic doll and the father of the atomic bomb over the years.
