September 18, 2025The Tech Skills That Command the Highest Salaries Are Constantly Changing
Have you ever wondered whether mastering rare but niche skills can boost your income as a developer? It reminds me of coin collectors debating rare low-grade coins versus common high-grade ones. Tech pros face the same choice: specialize in a rare, high-demand skill (even if it’s not widely adopted) or master more common, mainstream technologies?
The Rarity vs. Popularity Dilemma in Tech
In coin collecting, some argue true rarities hold value no matter their condition. Others prefer common examples in perfect shape. Tech has a similar debate:
Rare, Niche Skills (The “Low-Grade Rarities”)
- Legacy systems maintenance (COBOL, Fortran)
- Quantum computing development
- Blockchain architecture
- AI ethics and governance
Common, Polished Skills (The “High-Grade Coins”)
- JavaScript frameworks (React, Angular)
- Cloud architecture (AWS, Azure)
- Data analysis (Python, SQL)
- DevOps practices
Salary Potential: Where the Rare Skills Shine
Some coin collectors pay big for true rarities, condition aside. In tech, niche skills can bring huge paychecks too:
COBOL developers, often in legacy banking systems, can earn $150-$250/hour. Expertise is extremely scarce.
The Sweet Spot: Rare but Growing Fields
Your best career move might be spotting skills that are rare now but growing fast:
// Example: WebAssembly (WASM) specialists
// Currently rare but growing demand
const wasmDeveloper = {
salaryRange: "$180k-$300k",
demandGrowth: "+400% since 2020",
rarity: "Fewer than 10,000 experts worldwide"
};
Future-Proofing Your Career
Coin collectors wonder if low-grade rarities will keep their value. Tech pros must ask:
- Market trends: Will this rare skill still matter in 5-10 years?
- Transferability: Can this skill lead to other opportunities?
- Learning curve: Is learning this skill worth the time and effort?
Actionable Career Strategies
For Early-Career Developers
Start with common, high-demand skills. Think of it like collectors beginning with common coins. Then explore rarities.
For Mid-Career Professionals
Add one rare, high-value skill to stand out. Keep your core competencies strong.
For Senior Developers/CTOs
Find emerging tech where you can be an early expert. Help shape best practices as the field grows.
Balancing Your Skill Portfolio
Smart coin collectors mix rarity with quality and personal joy. Successful tech pros do the same:
- Core skills in high-demand areas (your “high-grade common coins”)
- Specialized knowledge in rare niches (your “low-grade rarities”)
- Ongoing learning to stay ahead as the market shifts
Coin collectors sometimes say their hobby is maddening. Tech career growth can feel that way too. But by choosing skills wisely—balancing rarity, demand, and future potential—you can build a career that pays well and feels rewarding.
