* I had a good seat to watch google obliterate mapquest and yahoomaps with amazing javascript maps. It was day and night. Yahoo was penny pinching their mapping engineers while Google was buying geographic satellite companies and innovating with lazy loading javascript maps. It went from, websites can't provide anywhere near the functionality of desktop apps to why would ever use a desktop app for that.
* I was building phone software and mobile search engines before, during, and after the launch of android so I got the inside perspective on cellular carriers reactions. Google was this a dinosaur ending asteroid to them and their wall gardens. They saw signs, then sky darkened and in their hearts they knew Google would build something 100X better than what they could ever build even if they wanted to give up their walled gardens which was a cognitive improbability. The carriers began going through the stages of grief, while they were still on anger, like the sound of thunder[0] android launched, and reality shifted under their feet. After that it seemed like nothing else had ever been possible or true.
Hungry Google was sight to behold.
