> a big part is that duckdbs spatial extension provides a SQL interface to a whole suite of standard foss gis packages by statically bundling everything (including inlining the default PROJ database of coordinate projection systems into the binary) and providing it for multiple platforms (including WASM). I.E there are no transitive dependencies except libc.

and for the last twenty, not ten years, this is what PostGIS was pioneering, and also teaching everyone get used to. DuckDB was not something that people even knew in GIS world. I'm not even sure whether QGIS connects to DuckDB, perhaps it does for a while, but it sure knows Spatialite for very long and last, but not least - ESRI sure as f*ck still have not heard of DuckDB. This is already half the geospatial world out there.

This whole article is superb biased and its very sad.
