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.
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.
