The video states that dimensionality reduction is needed because data can have too many dimensions, which can often become a curse. Reducing the number of dimensions helps make the data more manageable and easier to process.
Conditions: Applies when data has many dimensions.; Presented as an introductory motivation, not as a formal theorem.
