Yes, I absolutely agree that there is a problem with greed, ego and hubris in sillicon valley. Just wanted to point out that not all engineers fall in that category. I think that confidence in writing solid software when paired with humility can lead to good outcomes. To me, it seems like the ego and hubris issue can cause the most amount of problems when an individual (e.g. zuckerberg) takes on a savior and machiavellian complex. It seems like most of them actually believe that they are making the world better and they don't see the harm that their self interested blood thirsty capitalist side does at all.
