What happens when a world-changing technology attracts trillions of dollars in investment and how do you avoid being on the wrong side of the boom?

On this episode of the Women's Money Wisdom podcast, Melissa Joy is joined by Kai Wu, founder and chief investment officer of Sparkline Capital, for a thoughtful, data-driven conversation about AI and its real investment implications.

Rather than focusing on hype or fear, this discussion centers on capital allocation, specifically what happens when massive amounts of money pour into infrastructure. Using historical parallels like the railroads and the dot-com telecom buildout, Melissa and Kai explore why transformative technologies don’t always translate into transformative returns for the companies building the underlying systems.

You’ll hear what “CapEx” actually means, why AI requires unprecedented spending on chips and data centers, and how today’s market concentration around the largest tech companies creates both opportunity and risk.

This episode is especially helpful if you’ve benefited from recent market gains but are wondering about concentration risk, diversification, or how to think more strategically about AI exposure in your portfolio.

In this conversation, you’ll learn:

• Why a transformative technology does not automatically mean a great investment
• What capital expenditures (CapEx) are and why AI infrastructure is so expensive
• How past technology booms rewarded users more than infrastructure builders
• Why highly capital-intensive companies often underperform over time
• How S&P 500 concentration may create hidden portfolio risk
• What “AI early adopters” are and why they may offer overlooked opportunity
• How to think about diversification without abandoning innovation

Whether you’re managing significant wealth or simply trying to make smarter long-term decisions, this episode offers practical insight to help you think clearly — without hype, panic, or binary thinking.
