Why would I want to use a browser to do non broswery things? It's bad enough that we have to use browsers in the first place. Wouldn't we be better starting from scratch and developing a secure, standards-friendly way of deploying text, images and video rather than taking something which was designed to display just text and try and make it useful?

Any ideas?

I don't really have any ideas. Software distribution should be a solved problem by now but even if we limit ourselves to GNU/Linux on x86-64 computers, we can't agree on a distribution mechanism. We are all over the place from the blessed apt and yum to oh just curl this url and pipe it to sh (I am a n00b so I may have said it incorrectly). There is no good way to make sure everyone gets updated. It is a mess.

I am typing this on Mozilla Firefox but I can see the draws of Chrome as a platform. I personally love the distraction that working on the plumbing on different platform involves but I would rather the people who work on secure communications -- that journalists, politicians, and policy makers, and social influencers in general can trust with their lives -- not be distracted by the fun plumbing.

The way I see it, we have to abstract it at some level. If systems folks can't agree on a standard, then applications will standardize on apps that live on top of them.
