Stone age? Hardly. More like 18th century.
I am more worried that we do not have that many attempts at rebuilding, because coal and oil are finite. OTOH a slower 2nd iteration might actually work better than this one.
If we lost access to electricity, we'd be completely screwed; we can't even get drinkable water in many places without electricity.
For example where I live there is water around 10-20m depth, but it's polluted (it may be usable for agriculture but not for human consumption); you'd have to dig a well over 100m below the surface.
"I know others will disagree, but it's not something you wanna take a gamble on."
Far more important than 18th century vs stone age debate is the fact that there are people in charge that would lead us down either path.
