Rumors also suggest the upcoming MacBook might use the A18 Pro from the iPhone 16 Pro, a chip that benchmarks faster than the M1. Even if it only has six cores, making it slower for heavy workloads than the M2, an A18 Pro-powered MacBook would still be more than enough power for basic productivity work. Not everyone needs the surprising amount of GPU power in the MacBook Air — especially if downgrading means they can save $200 to $300.

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.
