MIT’s David Rotman notes that hyperscalers like Alphabet spent $120 billion last quarter despite a $5.9 billion free cash deficit, raising questions about AI’s return on investment. A survey of 6,000 executives found **90%** saw no productivity gains from AI over three years, while Workday’s research shows companies rework **40%** of AI-generated output, eating into savings. Meanwhile, Harvard’s Suraj Srinivasan found job postings for repetitive roles dropped **13%** after ChatGPT’s launch, while analytical and creative roles grew **20%**, with AI skills now required for augmentation-prone positions.\n\nThe studies suggest marketers who can prove AI’s ROI while preserving teams will advance. Rotman warns AI-driven job cuts could spark public backlash, while Srinivasan advises treating AI as a tool for collaboration—not cost-cutting. The authors emphasize tracking AI’s impact on hours saved, rework rates, and outcomes to justify investments. The research focuses on U.S. trends, leaving global and long-term effects uncertain.","keyPoints":["MIT study finds **90%** of 6,000 executives report no AI productivity gains over three years","Harvard research shows repetitive marketing roles declined **13%**, analytical roles grew **20%** post-ChatGPT","Experts warn AI-driven job cuts risk public backlash, urging marketers to track hours saved and rework rates"],"whyItMatters":"Marketers must prove AI’s ROI to avoid job cuts and secure promotions, as studies show productivity gains remain elusive while repetitive tasks vanish.","category":{"slug":"marketing","name":"Marketing & Small Business","url":"https://digestai.news/category/marketing"},"entities":{"companies":["MIT Technology Review","Harvard Business School","Alphabet","Workday","BetterUp Labs","Stanford Social Media Lab"],"models":[],"people":["David Rotman","Gary Gensler","Jessica Wachter","Kevin Indig","Ana Elena Azpúrua","Suraj Srinivasan"]},"firstPublishedAt":"2026-09-28T19:00:01Z","updatedAt":"2026-09-28T19:00:01Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Search Engine Journal","title":"MIT & Harvard Data Show How SEO And Paid Media Managers Become Directors via @sejournal, @gregjarboe","url":"https://searchenginejournal.com/mit-harvard-data-show-how-seo-and-paid-media-managers-become-directors/590669","publishedAt":"2026-09-28T19:00:01Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"MIT and Harvard warn AI’s productivity gap risks marketing jobs\", 28 September 2026, https://digestai.news/story/mit-and-harvard-warn-ais-productivity-gap-risks-marketing-jobs","publisher":"Digest AI","title":"MIT and Harvard warn AI’s productivity gap risks marketing jobs","datePublished":"2026-09-28T19:00:01Z","url":"https://digestai.news/story/mit-and-harvard-warn-ais-productivity-gap-risks-marketing-jobs"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
