Hence why 400 years was taken to get us back onto some moderate level of society.

At the cost of millions of life here and there.

I never read it as 400 years as a return to modernity. Just four-hundred after the fact. But this trivializes the matter as well, because after four-hundred years of coming back from the brink too, how would you propose returning to obtaining the raw materials needed to supply a modern society given that after a century of exploitation, much of the raw materials we can obtain it is only with engineering modern to our time?

The depths and capabilities of drilling for oil has been a process necessary to pursue supplies of oil found deeper underground. We cap entire mountains to dig out coal and iron. We have to go further and deeper, even for the primitive resources like iron and copper. The old world is economically devoid of much of the raw material for its own society from centuries of exploitation by ancient and medieval society, how do you expect to get anything new from the world? Or from where land - especially in the British isles - is at more of a premium now than it is today with much of the former arable land under water and to also keep on claiming mineral exploitation.
