Walmart (WMT) CEO's recent comments on AI's impact on jobs have investors and workers on high alert. Dan Geltrude believes AI will change the labor market landscape, with high-touch human jobs like bakers, drivers, and delivery workers being less at risk of automation. Geltrude thinks Walmart, Microsoft (MSFT), and Nvidia (NVDA) are well-positioned to adapt and thrive in an AI-driven economy, making them attractive long-term holds or buys. He also likes Target (TGT) in the retail space for its own AI investments.
