Economist Marc Sumerlin warns that the current AI optimism might lead companies to delay hiring, particularly affecting young workers (Gen Z), as they wait for the technology to prove its return on investment. This presents a significant negative implication of the AI boom, suggesting potential long-term unemployment or underemployment for a generation. The impact on the labor market could lead to reduced consumer demand and societal challenges. Investors should consider the demographic and labor market shifts driven by AI adoption when evaluating companies.
