We over-hired during COVID: Jack Dorsey after firing 4,000 Block staff citing AI

Former Twitter (now X) Co-founder Jack Dorsey said his fintech company Block "over-hired during COVID-19". "I incorrectly built two separate company structures...rather than one, which we corrected in mid-2024," he added. His remarks come after Block laid off over 4,000 employees, saying AI tools are enabling a new way of working.
