📊Harvard: IA Dá Mais Trabalho, Não Menos
"Mas a IA não ia nos libertar pra trabalhar menos?" Pois é. Segundo um estudo de 8 meses da Harvard Business Review com 200 funcionários de uma empresa de tech, o efeito foi exatamente o oposto. --- O que aconteceu: como a IA preenche lacunas de conhecimento, as pessoas começaram a fazer tarefas que antes seriam de outros departamentos ou terceirizadas. O trabalho se expandiu. As fronteiras entre funções se dissolveram - porque agora começar qualquer coisa é tão fácil quanto escrever um prompt. --- E tem o efeito cascata: especialistas passaram mais tempo corrigindo rascunhos feitos com IA e ensinando colegas. O ritmo acelerado virou expectativa. Sem pressão explícita dos chefes - só pela visibilidade do que agora é "normal".
Powerful new Harvard Business Review study. "AI does not reduce work. It intensifies it. " A 8-month field study at a US tech company with about 200 employees found that AI use did not shrink work, it intensified it, and made employees busier. Task expansion happened because AI filled in gaps in knowledge, so people started doing work that used to belong to other roles or would have been outsourced or deferred. That shift created extra coordination and review work for specialists, including fixing AI-assisted drafts and coaching colleagues whose work was only partly correct or complete. Boundaries blurred because starting became as easy as writing a prompt, so work slipped into lunch, meetings, and the minutes right before stepping away. Multitasking rose because people ran multiple AI threads at once and kept checking outputs, which increased attention switching and mental load. Over time, this faster rhythm raised expectations for speed through what became visible and normal, even without explicit pressure from managers.
