As technology advances, it becomes cheaper and more powerful. Companies such as Google and Facebook become worth billions by reaching billions. That is the key point that Bold makes: “the best way to become a billionaire is to solve a billion person problem.”
Entrepreneurs can, I am certain, make all of these advances happen and profoundly affect billions. We just need an exponential advance in humanity’s social consciousness so that technologies find roles in bettering humankind, not just in creating wealth for their founders and owners in the way that some Silicon Valley technologies do.
