Why did Marcel Duchamp and Francis Picabia become dissatisfied with Cubism?

Marcel Duchamp and Francis Picabia became dissatisfied with Cubism because they found the movement to be too systematic, static, and "boring".1

Both artists felt restricted by the conventions of the style and sought a more dynamic approach to art. Consequently, they moved away from the "semirealism" of Cubism toward a "nonobjective" expression of movement. This shift led them to explore concepts related to Futurism and Abstractionism, eventually contributing to the development of Dada, a movement that embraced absurdist humor and satiric, machine-like imagery to challenge bourgeois values.12
