William Blair industrials analyst Ross Sparenblek discusses how humanoid robotics could mark a structural shift in productivity by extending AI’s capabilities from digital tasks into real-world physical labor. He outlines the key forces accelerating adoption, from demographic pressures to supply chain dynamics, while highlighting both the long-term opportunity and the technical and scaling challenges still ahead.

Welcome to The William Blair Thinking Podcast, the podcast series that aims to provide in-depth expertise from our award-winning equity research and capital advisory teams on today's financial and economic landscape. I'm Chris Thonis, head of Equities Marketing and Media Relations, and I'm delighted to be your host. Hi everybody, welcome back to William Blair Thinking Presents. Today is June 9th, 2026. I'm joined by Ross Sparrenblack. He's the research analyst in William Blair's industrials group, where he covers diversified industrials with a

focus on robotics and automation. Ross, thanks for joining us. Hey Chris, thanks for having me. Happy to be here. So today we're discussing your team's latest industry report. It's called Race to Infinite Labor, The Humanoid Hypothesis. To start, can you just give us a high-level overview of what the report is focused on and then why the topic is relevant right now?

Yeah, yeah, certainly. Our report focuses on one of the next major inflection points in the robotics market, which is the shift from static automation, which handles narrow, repetitive tasks to robots that can handle broad physical work that defines most of the global economy.

If you go back the last several decades, we've seen incremental improvements with each new wave of robots. By and large, physical labor has remained untouched. AI is transforming this on the digital side, everything from coding to customer service and even creative roles.

But we haven't really bridged that gap to real-world physical execution. But this is what Humanoid are set to provide and specifically close that gap between planning and doing. And we see that the reason this matters right now is that when you think across the core economic drivers, productivity seems to have the highest torque to sustain that economic growth.

You know, you walk through a number of structural forces in the report. When you step back, what are the biggest shifts you're seeing that make this moment feel different or more urgent than prior waves of automation? Certainly. There are several structural headwinds that are working not only against the West, but many develop economies today. Aging populations are top of mind and most obvious. The U.S. is expected to see something around 2030.

Children outnumbered by adults for the first time and also given the limited traction with China's two-child policy. The country is on course to undergo the largest absolute population decline over the next several decades. But at the same time, governments and corporations are also looking to reshore and dual-source the global supply chain following the aftershocks of COVID and the supply chain bottlenecks, which just further compounds the need for more localized labor.

And then you consider the burden of rising national debts, growing energy scarcity from the ramping data center build to power AI. It all points back t...
