for sure there will be a subset of humanity looking back and shaking their heads, and some of them will even have legitimate reasons for doing so. for instance, our brazenness around (bio-)chemistry, given that we are at the very beginning of that vast learning curve. that includes drugs, synthetic materials, fuels, combustion byproducts, you name it.

but yes, it's highly unlikely that they could shake their heads at every instance of today's ignorance and hubris in totality.
