Good piece which subtly reminds us that while ideas can be distilled and over simplified, it's the execution that carries it forward. Looking forward for the next piece!

(also: "I've been on this industry for X years and make $Y per year, Z ebitda…" means jack all when the status quo is broken and the model is re-written. Cool stuff!)
