Now that last sentence though:
>>Still, this is a reminder that we've all failed to create a better world with technology.
You cannot[1] say tech has given the world a net negative. This is all pedantic though because the bottom line is the protesters are upset and emotions have boiled over striking anyone that happens to be nearby. Right now, that's Google. Please Google and its employees, don't respond in a way that'll make this whole thing blow up more than it already has. The protesters do have a point; they're just not venting their anger in the best way possible. Their focus on Google will makes tech-people forget the bigger picture and start thing about "Why Google?" "Why this G-employee?"... and then we start down the path of crazy-town where there is no positive-outcome.
1. I do realize this is potentially debatable given the invention of stuff like the atomic-bomb. But let's not go there. As long as we haven't blown ourselves up and out of existence, tech is a net positive.
