Broadcom's AI Chip Story Might Be Telling Us Something We Don't Want to Hear
Morgan Stanley's CIO thinks the semiconductor rally is built on a misunderstanding, and honestly, I'm starting to wonder if she's right.

I want to believe the AI chip boom is real. I really do. After years of covering humanoids and embodied AI, I've seen how desperately this industry needs better silicon, faster inference, cheaper training. The semiconductor surge feels like it should be the foundation of everything that comes next.
But then someone like Lisa Shalett comes along and makes me second-guess myself.
Shalett, who runs investment strategy at Morgan Stanley Wealth Management, said something at Bloomberg Tech 2026 this week that's been rattling around in my head. She called Broadcom "a warning flag" for the broader market. Her argument, and I think it's worth taking seriously even if you disagree, is that investors are confusing pricing power with productivity.
Let me try to unpack that, because I initially didn't fully get what she meant.
The semiconductor companies have been posting incredible numbers. Broadcom's CEO Hock Tan was at the same conference, talking up demand and revenue outlook with the confidence you'd expect from someone whose stock has been on a tear. And look, the demand is real. Companies are buying these chips. The orders are there. Nobody's disputing that.
What Shalett is questioning is whether the prices these chips command actually reflect sustainable productivity gains, or whether they're just reflecting temporary scarcity and hype. It's the difference between "this chip makes your AI system 10x more efficient" and "this chip costs 10x more because everyone's panicking to buy before they sell out."
You might be wondering why this matters for robotics specifically. Here's the thing: embodied AI is completely dependent on this semiconductor ecosystem. Every humanoid, every autonomous system, every piece of edge inference hardware, it all runs on chips that are currently priced like they're made of something rarer than gold. If that pricing is built on a misunderstanding rather than genuine productivity improvements, we've got a problem.
