Programmers that will define the next decade

AI is driving a renaissance in programming, shifting the ideal developer archetype from the T-shaped generalist to the 'polymath' — someone with depth across multiple complementary skills. Two polymath types are identified: the technical polymath (deep across multiple tech domains like backend, security, and databases) and the domain polymath (who applies programming skills to solve problems in a specific non-tech field). The key differentiator is depth of knowledge, not just breadth. Building extensively and understanding the abstractions beneath your stack are recommended paths to developing that depth. Fun and genuine curiosity are framed as the most important long-term success factors.
