Of course that is pretty much 1% of the journey. Turning that light-bulb moment into an actual product, getting mass market adoption, finding the killer app, that's hard. And anonymous. Keeping customers happy is hard. But again, anonymous.
Are you more impressed with a CV that says "invented iphone" or one that says "worked on iphone 2 to make it better than iphone 1"? Or worse yet "accumulated customer feedback to improve iphone 1, worked with team developing iphone 2"?
So it's not just google (although magnified there.) It's everywhere. You remember who _invented_ the light-bulb, but you've no idea of the people who developed that into a product, with manufacturing, distribution, sales and developed bulb-connector-standards and so on.
In our business it's the same. Here's a new wizz-bang feature. 100% glory. Maintaining feature for the next 20 years, adapting to ever-changing world requirements, keeping customers happy, and using it - anyone can do that. (and nobody wants to - it's too much like hard work.)
