Well, that's an entirely fair way of looking at it. Pshaw! A few years of war held less innovation than a hundred!

A working telegraph over 8 miles was invented in 1816.

typewriter 1829

telephone 1876

light bulb 1879

skyscrapers ~1890ish... but preceeded by buildings with similar number of stories from Roman times!

Yes, you're quite right. A hundred years (two thousand, if you include Roman precedent) does indeed hold more innovation than four.

And if you characterise ~98 years ('period just before WWI' with examples, 1816-1914) as 'slightly longer than WW2', which came in at 6 years (5 in earnest, 4 if you're American), perhaps you should pursue a career in archaeology, paleontology, or politics...
