The practice of AI companies secretly buying millions of old books (some vanishingly rare), scanning them for AI training, then destroying them, epitomises everything that is wrong with today's exploitative AI industry.
It is ill-gotten gains being used to exploit legal loopholes and subsume culture, all protected from public criticism by NDAs.
This should not be legal, and it is a travesty that it is going unpunished.

Since nobody called it out in the comments, this “new way” to show 3D Gaussian splats is a basic 19th century construction, studied by Jakob Steiner and others, called a “sphere inversion” or “Möbius transformation”:

It looks good because it is an example of a so-called conformal map, which preserves angles, but distorts scales. However, when you look at something up close, it doesn't really matter what its absolute scale is (whereas angular distortion is far more noticeable).
Conformal maps, namely the 16th century Mercator projection (old as it is) remains the projection of choice in Google Maps and other mapping tools, since it is the unique map that (i) preserves angles, and (ii) keeps north pointing "up" everywhere on the globe.
The 3DGS scheme shown here is just bumping up the usual approach up one dimension: apply a conformal projection; keep the "up" direction fixed. The specific choice of conformal maps (inversions in the sphere) are in fact the only choice available in 3D, due to Liouville's theorem on conformal mappings.

Released in 1967, Viy was the Soviet Union's first officially released horror film. Its breathtaking practical effects—created by fantasy pioneer Aleksandr Ptushko—remain among the most imaginative ever put on screen, culminating in one of horror's greatest supernatural finales.
Lo más perturbador de Philip K. Dick no es lo que imaginó. Es que en 1974 tuvo una experiencia que no pudo explicar con ningún marco racional y pasó los últimos ocho años de su vida escribiendo 8000 páginas intentando entenderla. No lo consiguió.
En esta escena, Orfeo entra al inframundo y calma al perro guardián Cerbero tocando su lira, lo que permite a Caronte dejarlo subir a su barco. Extracto de un cortometraje animado (1984) de Leslie Keene inspirado en pinturas de jarrones de figuras rojas.
