The sequence that matters
Most people approach this backwards — they reach for tools before building foundations. The effective sequence runs the other way: understand the monetary properties of Bitcoin before you touch a wallet. Understand how language models reason before you build an agent. Understand prompt engineering before you reach for an orchestration framework.
The foundations are not optional prerequisites to skip. They're the reason experienced builders make better architectural decisions than people who learned by copying tutorials. The gap between someone who understands attention mechanisms and someone who doesn't shows up immediately in how they design agent workflows.
The good news: the foundational courses on Coursera are among the best educational content produced in the last decade. Andrew Ng's deep learning specialisation. The AI for Everyone course. Princeton's Bitcoin course. These are not filler — they're the real thing.
