La Grande Dune du Pilat

Southwest of Bordeaux in France stands Europe’s tallest sand dune, La Grande Dune du Pilat. Some 2.7 kilometers long and over 100 meters high, this dune took shape here over thousands of years. It moves inland a few meters every year as winds blowing from the Atlantic push sand up its shallow seaward side to the dune’s crest. There, sand will avalanche down the steeper leeward side, advancing the dune little by little. The dune’s accumulation has not been steady; during cooler and drier times, sand has collected there, but it took warmer and wetter climes to grow the forests that have helped stabilize the soil and build the dune higher. Humanity has played a role as well, at times introducing new tree species to stabilize the dune. (Image credit: W. Liang; via NASA Earth Observatory)

I am almost missing the good old days in which retired engineers or new undercover Einsteins used to sent me their theories of everything (without equations, or with un-intelligible scribbles etc).

Now instead, they send me "their interesting conversations with Grok/ChatGPT" and I just want to cry in despair.

The #AI bubble has even managed to ruin the fun in #retired_engineers, and I cannot forgive the AI hype for this (besides other things).
