Silicon Valley ain’t doing shit to make the world a better place

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).

Singularity University is dedicated to solving long term global problems.

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.

Furthermore, the "best/most helpful" inventions often come from people not at all interested 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.

Off the top of my head, I can think of one counter-example to the title: Tesla.
