Artificial intelligence remains the defining investment narrative of the decade, propelling companies like Nvidia, Broadcom, and Micron to record valuations and driving the S&P 500 to successive highs. But as enthusiasm builds, so do concerns about speculative excess. In a recent episode of Zero Sum, Dr. Richard Peterson, behavioral economist and founder of MarketPsych, offered a nuanced perspective on the AI trade, arguing that the technology will ultimately create more jobs than it eliminates.
AI Rally Backed by Real Profits
Peterson pushed back against comparisons to the dot-com bubble, noting that today's AI leaders generate substantial revenues and cash flows. "Nvidia has enormous profits, Micron is making tremendous margins, so there's real money, versus in the dotcom boom there wasn't real revenue coming in," he said. However, he cautioned that this does not eliminate bubble risk. Technological revolutions typically follow a pattern where early winners enjoy extraordinary profitability before competition intensifies.
Competition is already emerging from rival chipmakers, custom silicon developed by hyperscalers, and increasingly capable Chinese alternatives. The key question for investors, Peterson argued, is whether current valuations leave enough room for margin pressure as more players enter the market.
Sentiment Shifts Before Prices
Rather than relying solely on earnings forecasts, Peterson studies investor psychology. MarketPsych monitors roughly 1,000 premium news outlets and dozens of investment-focused social media platforms across 28 languages, creating a historical record of sentiment since 1998. One consistent pattern: optimism typically peaks early in a market cycle before gradually fading, even as stock prices continue climbing. Social media often turns skeptical before traditional financial media, providing an early signal that expectations may be outrunning reality.
While sentiment alone is not a prediction tool, it offers valuable context when enthusiasm becomes one-sided. Peterson pointed to leveraged single-stock ETFs and a growing pipeline of AI-related IPOs as signs of speculative froth. Potential listings from companies like OpenAI and Anthropic, following SpaceX's high-profile debut, could eventually reduce speculative capital available to existing market leaders.
AI Will Create More Jobs
Addressing one of AI's biggest societal concerns, Peterson argued that the technology will create more jobs than it destroys. He cited rising software engineering vacancies and research showing that companies adopting AI are often expanding headcount elsewhere, rather than simply replacing workers. "I think AI will create more jobs, and I think that's what we're seeing," he said. The challenge lies not in whether AI creates employment, but in how quickly workers and businesses adapt to changing skill requirements.
Where to Look Next
Peterson believes investors should look beyond headline AI names. Networking companies, optical infrastructure providers, and semiconductor equipment manufacturers remain well positioned as AI infrastructure expands. However, he warned that some memory makers and server manufacturers are beginning to exhibit elevated sentiment typical of late-stage rallies. He also expressed growing optimism about nuclear power, solar, and battery storage as long-term beneficiaries of the AI buildout.
