When I got my kid some time ago I remember how quickly I realized my productive time in life just got reduced by magnitudes. For sure, probably it's not the late night debugging sessions that I'll remember when I'm old - but still. Anyways this freaked me out in a way that suddenly all personal growth had to count. No more making "another web app" or "another game". It has to be deep and dense. And that made me realize that the decade of business app development experience is quite far from system level software. Which is the reason I'm looking for ways to contribute - where a community can help with the context.
