Competing to be the absolute best in one popular domain is a losing game for most. A more strategic approach is to become good (top 25%) at two or more rarely combined skills. This 'skill stacking' creates a unique specialty where you can become the #1 expert with far less competition.

Instead of being a generalist, the best way to stay valuable is by combining deep skills. For example, a PM who can also design, or an engineer who is highly product-minded, becomes a "unicorn" in an AI-augmented team. This interdisciplinary spike makes you far more valuable and less replaceable.

The best career paths are now found at the intersection of two seemingly unrelated disciplines. This "bilingual" approach creates a unique perspective and value that cannot be easily replicated by others with traditional, siloed expertise, like a pediatric surgeon who is also a game developer.

Inspired by Dilbert creator Scott Adams, the key to career success is combining skills. Being a cartoonist who understood business was a rare combination. AI makes it easier to develop a second or third deep skill, transforming you from a replaceable specialist into an invaluable, multi-talented individual.

Don't just deepen one skill; combine multiple rare and complementary skills. A finance expert who also masters YouTube content creation becomes uniquely valuable, dramatically increasing their earning potential by occupying an uncontested niche.

To thrive in the AI era, go beyond a "T-shaped" profile. Develop deep expertise in one core skill and strong proficiency in two or more adjacent ones (an "E" or "F" shape). This combination makes you non-fungible and irreplaceable, as economist Larry Summers advised.

Instead of striving to be the best in a single domain, find a unique intersection of skills you're good at. Being able to negotiate across both design and engineering, for example, creates a niche where you are the "only" person with that combination, making you more valuable than being just another "good" specialist.

The traditional advice to "pick a lane" is becoming obsolete. In an era of disruption from forces like AI, a multi-hyphenate career built on curiosity provides a broader skillset and adaptability that is more valuable than deep, narrow specialization.

The era of deep specialization is over. Career durability now comes from being proficient (in the 70th percentile) across multiple vectors. Instead of being a master of one, aim to be a 'jack of all trades' by finding a valuable intersection of three strong skills.
