I don't follow bitcoin much, but shouldn't every popular community project be essentially swimming with cash (or at least bitcoin) these days? On the other hand I guess the same could be said about the tech boom.
As far as I know there is no lack of female hackers in movies nor of creative girls and women in real life. Take the electronics/maker scene. Even though there is even less women in EE/ME than software (which is quite the feat in itself) I can think of at least half a dozen public women in what little scene there is. Software culture is much more subjective and largely based on things that doesn't exists anymore. And even if it did it would to a large extent have been created by and for men. If we want more women in software culture it has to be about making cool things and not about fitting into stereotypes.
Authentication mostly. The lack of which is the major reason why the majority of us are still typing passwords into boxes in the browser and send them over the Internet in contradiction to best practices. Doing away with that would potentially solve a lot of problems, like phishing, but also replace cookies. Meaning it would be much harder to track users across the Internet threatening not only the revenue of major player but also their dominance since being able to handle security issues is a major advantage for them. So instead of fixing the problem at the source, we have security people recommending password managers and the EFF making cookie blockers.
Essentially every geek I have ever talked to support standards, decentralization, community efforts etc. Yet, here we have the company that has more influence than anyone else over the Internet almost single-handedly designing the protocol.
This is just depressing. Sure, sell us out to big corporations by not implementing proper features in protocols like HTTP/2 so we can get tracked for decades to come. Yet, represent freedom by yet another cool way to "fool" governments. When historians look back at what happened to the Internet, or even society, they are going to find that organizations like the IETF was to busy with romantic dreams of their own greatness to serve the public. It's like people leaned nothing from Snowden.
