When this applies
when a successful organization considers diversifying away from the business where it holds a dominant advantage
The takeaway
If you are already the best at the business with the brightest future, resist the pull to diversify into markets where you're merely average.
Why it works
Diversifying into unrelated markets where you lack the same accumulated advantage dilutes focus and underperforms relative to doubling down on the business where your moat is strongest.
One level up
Advantage compounds fastest where it's already concentrated; chasing diversification can destroy compounding.
Where it stops holding
This stops working when the core business's growth is genuinely capped and diversification is necessary for survival, not just opportunistic expansion.
Detail
situation: TSMC at points tried to exit/diversify from integrated circuits into solar and memory businesses.
decision: Chang concluded none of those alternative businesses were as good, and that the key insight was: you're already in the best business, so stop chasing others.
outcome: TSMC refocused on integrated circuits, which Chang argued were the future; the hosts explicitly apply the same logic to themselves ('we're already doing the thing we should be doing... we should always just make another [episode]').
lesson: Recognizing you're already in your best business, and resisting diversification, can be more valuable than chasing adjacent opportunities.
In their words
The key insight was: you're already in the best business. Integrated circuits are the future and will be for a long time. And you're already the best at them. So stop trying to do other things and just do that really well.
