There’s a debate happening in boardrooms across Silicon Valley that I think is being framed completely wrong.
The question isn’t whether older board members can keep up with fast-moving tech companies. The question is whether you can afford to build a board without them.
The instinct to load a tech board with 35-year-olds is understandable. Speed feels like a young person’s game. But that instinct is built on an assumption that a new Yale School of Public Health study directly challenges.
Researchers Becca Levy and Martin Slade tracked 11,314 individuals aged 65 and older for up to 12 years. What they found runs counter to nearly everything Silicon Valley assumes about older people: 45.15% of participants actually improved in cognitive and/or physical function over the 12 years after age 65. Not maintained. Improved. And those who held positive age beliefs were significantly more likely to show that improvement — cognitively and physically both.
[Email readers, continue here…] The “inevitable decline” narrative turns out to be exactly that — a narrative, not a law.
So what does this mean for board composition in a fast-moving tech company?
It means the real question isn’t age. It’s what each person at the table actually brings.
A seasoned board member who has navigated three recessions, two market bubbles, and one company near-death experience carries a pattern library that no amount of raw intelligence shortcuts. They’ve watched founders make the same three mistakes in every cycle. They’ve seen which pivots work and which ones just burn runway. They know what a real term sheet looks like versus a trap disguised as one.
What they often lack is fluency in the current technical stack, current go-to-market motion, or current consumer behavior. That’s real, and it matters. The answer isn’t to ignore it — it’s to build a board where those gaps are covered by other members who complement rather than duplicate.
Charlie Munger (Berkshire-Hathaway) led at least one board well beyond his 90th year.
The best boards aren’t age-homogeneous.
They’re intentionally mixed. Deep experience sitting alongside current-market fluency. Crisis pattern recognition alongside product instinct. The Yale research doesn’t just challenge ageism in healthcare. It challenges the unexamined assumption that a 67-year-old in your boardroom is working with a declining asset. In most cases, they’re the most compounded one in the room.
