I'll expand upon that.

The article claims not many people creatively think of new solutions to existing problems.

But the problem is that of the people who do think creatively fewer have the energy and determination to actually do something with the idea. And of those even fewer are successful.

The only redeeming quality to the article is the mentioning of certain research in creative thinking: "Theory of Solving Inventor's Problems, the Blue Ocean Strategy, the Theory of Constraints, and in modern works in cognitive psychology."

These may be interesting for people looking to expand their problem solving skills/creativity. But the article claims they are the snake oil to hi-tech startups.
