"Each incremental company, to some extent, dilutes the values of others." I take issue with this point in the article as it assumes competition. While there is competition obviously, many start ups are actually complements for other companies. It is entirely possible that many of the start ups "competing" with each other actually thrive on the success of others and even increase the success of other companies through their existence. As an example, think about a company like Heroku, and Amazon. Heroku makes using AWS easier, so Amazon rents more time and servers to Heroku while Heroku also makes money that otherwise wouldn't have been made. These relationships exist all throughout the business world and are good, not "bubble" influences.
