For years, Jack Dorsey preached radical minimalism, and now he’s applying that philosophy to his org chart. The CEO of BlockXYZ

, formerly Square, announced plans to nearly halve his workforce, claiming AI is “enabling a new way of working.” Markets rewarded the bold move with an 17% surge on Friday, with Dorsey believing “the majority of companies will reach the same conclusion.”

also pointed to AI when trimming staff. Dorsey predicts more layoffs within a year, adding he’d “rather get there … on our own terms than be forced into it reactively.” If he’s right, giants like SalesforceCRM

could already be drafting their own minimalist manifestos. Then again, after years of overhiring, tech’s newfound passion may owe more to cleanup than philosophy.
