我买东西，有选择困难症。看中的东西，不能马上下单，跟冬截然相反。这个事我反复想过，也属于早期创伤。生病后，我的选择困难症明显减轻了。扁鹊说，不治有病，治未病。这句话听着别扭，未病你治啥？其实他的意思是，病就是个标签。打个喷嚏流个鼻涕就大惊小怪，那根本不叫病。天下本没有病，说的人多了，就真有了病。我不爱吃药，裹着蜜的大药丸子偶尔吃几个，不为治病，为好吃。
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.

Can these agent-benchmaxxed implementations actually beat the existing machine learning algorithm libraries, despite those libraries already being written in a low-level language such as C/C++/Fortran? Here are the results on my personal MacBook Pro comparing the CPU benchmarks of the Rust implementations of various computationally intensive ML algorithms to their respective popular implementations, where the agentic Rust results are within similarity tolerance with the battle-tested implementations and Python packages are compared against the Python bindings of the agent-coded Rust packages:
