Chain Stratagems

I did not understand this until I saw it happen in real time with people I know. I kept thinking depth would be the answer because that is what worked for my generation. The half-life of professional skills is collapsing. A 2023 McKinsey analysis found that technical skills now depreciate at 2.6 years on average, down from 10-15 years in 1987.^[1] Your child will not build career security by mastering one domain deeply. AI closes that gap too quickly.

Even prestigious single skills face commoditization. Legal research, financial modeling, diagnostic radiology, software testing. All have seen AI systems match or exceed median human performance in controlled settings.^[2] The programmer who only codes well is competing with Claude and GitHub Copilot. The analyst who only manipulates spreadsheets is racing against tools that interpret natural language queries.

But here is what remains scarce: the ability to combine skills from different domains into integrated problem-solving. A Stanford study tracking 12,000 professionals over eight years found that workers with competencies spanning three or more distinct categories, technical, interpersonal, and creative, experienced 47% less wage stagnation and 73% lower risk of role elimination during automation waves.^[3]

Your child does not need to be the best coder. They need to be good enough at code, strong at communication, and curious about how systems interact. That combination, those chains, create compound advantage AI cannot easily replicate. The question is not what should my child master. The question is what three capabilities, stacked together, make them irreplaceable.

Scott Adams, creator of Dilbert, has written about being in the top 25% of cartoonists, top 25% of comedic writers, and top 25% of people who understand business. None of those skills made him exceptional alone. Combined, they made him nearly unique.^[4] This is the mathematics of skill compounding.

The World Economic Forum's 2024 Future of Jobs Report identifies a pattern across resilient careers: professionals who thrive combine a technical foundation with what researchers call bridging competencies, skills that translate between domains.^[5] An engineer who writes clearly. A designer who understands code. A teacher who thinks like a product manager.

OECD data from 23 countries shows that workers demonstrating competence in three categories, analytical reasoning, interpersonal coordination, and adaptive learning, earn 34% more on average than peers with equivalent education but siloed expertise.^[6] The premium is not for knowing more. It is for connecting what you know in ways others cannot.

For your child, this means rejecting the trap of hyper-specialization. The path forward is not to become the world's expert in one narrow thing. It is to develop three strengths that rarely appear together, then position themselves at the intersection. A biologist who codes and writes. A mathematician who designs and teaches. A historian who analyzes data and tells stories. Chains create moats.

Your child's career will not be won with a single devastating move. It will be built through deliberate combinations that others do not see coming.

Start by mapping your child's existing foundation. What do they already do well? Not what they love most. What do they demonstrate competence in without excessive struggle. This becomes anchor skill one. It does not need to be rare. It needs to be solid.

Next, identify an adjacent skill from a different category. If the anchor is technical, the adjacent skill should be interpersonal or creative. If the anchor is verbal, choose something spatial or analytical. The goal is productive distance, close enough that learning transfers, far enough that the combination feels uncommon. A child strong in math might add public speaking. A writer might learn basic data visualization.

The third skill completes the chain. MIT research on innovation teams found that breakthroughs most often came from groups combining three distinct knowledge bases, not two.^[7] Two skills create competence. Three skills create asymmetry, an unfair advantage competitors cannot easily copy. The child who codes, writes, and understands psychology has options the pure computer scientist does not.

These chains take years to forge, which is exactly why you start now. A 2024 Burning Glass Institute analysis found that professionals with documented tri-domain capability spent an average of 4.8 years building that profile but experienced 89% lower risk of role displacement over the subsequent decade.^[8] You are not building for next year's resume. You are building for 2035.

I almost made exactly this mistake with my 13-year-old. She is strong in math and I immediately started researching advanced programs and competition tracks, ready to pour everything into making her exceptional at this one skill. The mistake is optimization for depth when the future rewards combination. Parents see their child excel at one thing, music, math, debate, and pour all resources into making them exceptional at that single skill. This was correct strategy in 1995. It is catastrophic in 2025.

Depth still matters. But depth without breadth creates brittleness. Your child becomes exceptionally good at something AI will eventually commoditize, with no adjacent capabilities to fall back on. They are a single point of failure in their own career.

The second mistake is building chains randomly instead of strategically. Three unrelated skills do not create compound advantage. They create a confused resume. The chain must make narrative sense. The combination must answer a question the market is asking, or will ask soon. A child who plays piano, runs track, and knows chemistry has three skills. But they do not form a chain. A child who understands human behavior, analyzes data, and communicates clearly has built something integrated and rare.

Your job is not to make your child the best at one thing. It is to help them become uncommon through combination, to stack capabilities that multiply value instead of simply adding it. Start with what they have. Add what they need. Link the chain before the future demands it.
