about how to make people click ads
Best minds of any generation have always thought about ways to make money.That doesn't mean that the world doesn't benefit from side-effects. Information is at your fingertips because of companies like Google and Yahoo. Staying connected is easier then before because of companies like Facebook and Twitter.
And speaking about infrastructure; since 2000 lots of cool things happened, like cheap cloud-computing (EC2, Rackspace) or open-source projects that can kick start your company straight at Google-scale if needed (Hadoop). Not to mention research papers that happened because of these companies.
