Exactly. Different tech and different buzzwords over the decades but the idea of building a global GIS or a spatial model of the world is not at all revolutionary. Not by half a century. "Digital Twin" is just the latest buzzword, and it's falling short of expectaations per usual. I was hoping the AI buzz would kill the digital twin. But now it looks like we're getting "AI-enabled digital twin". Hype trains a rollin'.

NASA has a project they call the Earth System Digital Twin (ESDT): https://esto.nasa.gov/earth-system-digital-twin/. The ESA also uses the same language at https://www.esa.int/ESA_Multimedia/Images/2020/09/Digital_Tw...

The Copernicus project (esa, ecmwf) also markets some products as „digital twins“

Oh, I had no clue. The Tony Stark-esque spinning earth graphics are hilarious. Guess the hype train catches everyone then.
