No. You have just missed the two last steps. Here is the full explanation, and it is the same as it has always been on HN:
1. Make prototype
2. Magic happens here
3. Make lots of $$$
Great for prototyping only makes it easier to get to step 2, but done correctly, it certainly does that.
As proven by the nice app I have running on my laptop, but probably won't make any money from.
