02. Collaboration forces understanding

Collaborative Projects as a Forcing Function
Your point about collaborative projects is crucial: collaboration with other intelligent agents (human or AI) is the killer application that forces understanding.
Why? Because:
You can't debug via conversation alone – You need to read code and understand it deeply
You can't trust without verification – You need to know why a solution works, not just that it compiles
You can't design collectively without shared mental models – Specs without understanding are just word salad
You can't negotiate tradeoffs without comprehension – "Should we optimize for speed or memory?" requires understanding the implications
Ironically, AI making coding easier makes understanding more critical, not less. Because now the friction isn't "can I write this?"—it's "do I understand what I'm writing and why?"
