Don’t most technological breakthroughs serve the elite first? The Ford Model T wasn’t sold to the middle class first, although Henry Ford’s vision for the automobile was an affordable car for most Americans. The iPhone was and has never been for the poor. Solar panels regardless of the installation company still cost a lot and most people installing them rely on government incentives to make them less cost-prohibitive.
So what’s the point you’re making? Technology costs a lot to develop that’s why there’s VC firms. Musk is just bypassing that middleman.
