I was thinking about how we dont use film anymore to take pictures, we dont use paper to write. Most everythign is done digitally now. People have a whole life worth of pics on their phone, and computer. People have writings on their computers. If we ever get a good solar flare that wipes out our grid and kills our electronics, it will all be wiped in an instant. Whole lifetimes of photos gone. Entire volumes of writing gone.
In the distant future people will think that we were in the dark ages a generation without art, without writing. An unadvanced society.
Then a million years from now when we are long gone and we are just one of the layers beneath the soil. If someone excavates all they will find is a layer of plastics and toxins.
We are leaving one hell of a legacy on this planet.
