The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.

If you want something fully split with thumb clusters and a columnar layout but that’s a little less minimal than the Zsa Voyager— and wireless to boot — the Advantage 360 from Kinesis, makers of the popular Advantage 2 is a good one to check out. It looks like it comes from an ‘80s-era IBM office, but is somehow also from the future. The tenting goes from low to intense and the key well curves concavely to meet your fingers where they naturally land. The 360 is per-key programmable, works with layers and has four macros keys.

Mass domestic surveillance. We support the use of AI for lawful foreign intelligence and counterintelligence missions. But using these systems for mass domestic surveillance is incompatible with democratic values. AI-driven mass surveillance presents serious, novel risks to our fundamental liberties. To the extent that such surveillance is currently legal, this is only because the law has not yet caught up with the rapidly growing capabilities of AI. For example, under current law, the government can purchase detailed records of Americans’ movements, web browsing, and associations from public sources without obtaining a warrant, a practice the Intelligence Community has acknowledged raises privacy concerns and that has generated bipartisan opposition in Congress. Powerful AI makes it possible to assemble this scattered, individually innocuous data into a comprehensive picture of any person’s life—automatically and at massive scale.
