Apple single handedly created a multi billion dollar industry, giving aspiring developers like me a big career opportunity, and people worldwide access to brilliant and standardized tools (medical field alone is chock full of them).<p>Singularity University is dedicated to solving long term global problems.<p>Many education startups (including mine) aim to change how basic subjects are taught and understood globally, increasing global ability and opportunity for everyone with access to a computer.<p>Furthermore, the "best/most helpful" inventions often come from people not at all <i>interested</i> in that space - physicists with no interest in any commercial tech field discovering QM which led to the modern computer the most prominent example of this - so even if we didn't care about the world (which many of us do), the side effect of progress is that it makes more things possible for everyone.
