How to Build Skills That Outlast Any Tool (From Data Analyst to AI Lead)

Tools change and frameworks die, but your career doesn't have to. Marijn Markus joins the show to explain why "Don't be a fool with a tool" is the single most important piece of advice for modern software engineers and data professionals.

In this episode, we cover:

  • The "Meta-Skill" of learning how to learn new technologies
  • Why real innovation often originates in "dark" industries like crime and warfare
  • How to future-proof your career against AI agents and automation
  • Why understanding the business problem is more valuable than writing the code

This conversation is essential for engineers who want to move from memorizing syntax to mastering the skills that actually last.
