And the free-will-is-an-illusion camp would have you continue to trace that back from why was the act of delegation made (probablistic) to the big bang. Implying that humans can also not make decisions.

London Falling, fascinating story about a piece of London's underbelly. Same guy that wrote Say Nothing, which is also great.

Replit is used a lot in this context. Their agent is good, but their circumvent-policies-to-get-something-in-front-of-execs-quickly is an amazing and mis-priced feature.

Goldman has done this for decades, pushing it even further by having developed their own language (Slang), graph db (SecDB), and IDE (SecView). Many engineers resist working it in, but for any strat it's mandatory.

If this and/or the policies, leadership, and mindset that enable these kinds of things interest you, I highly recommend Abundance by Ezra Klein and Derek Thompson. IIRC, they outline data centers in space in his utopian introduction.

What the "right answer" is will vary widely on application and analyst. That's one reason there are so many coordinate ref systems. If you keep everything in 3857, you'll get answers in ~meters, but whether that's "right" depends on where and how large the distance or geom is and what your precision threshold is. So, really, everyone's needs are necessarily "specific."

DuckDB > geopandas, certainly for anything out of core. Though, I recently gave up on importing 70GB worth of large multipolygons (from a csv in hex wkb), and just used a postgis container. In concert with DuckDB's growth, I'd also mark the advent of geoparquet.

The big change, in my view, over the past decade in GIS software, is in compute and storage efficiency across the typical stack. DuckDB has become a part of this, but h/t to the advances from shapely, geopandas, geoparquet, and GDAL. There's a lot of overlap in that venn diagram, and credit should be spread around. QGIS is great, too, though I feel there is market opportunity to apply 90/10 to its massive feature set and move it to the web.
