NFAs are cheaper to construct, but have a O(n*m) matching time, where n is the size of the input and m is the size of the state graph. NFAs are often seen as the reasonable middle ground, but i disagree and will argue that NFAs are worse than the other two. they are theoretically “linear”, but in practice they do not perform as well as DFAs (in the average case they are also much slower than backtracking). they spend the complexity in the wrong place - why would i want matching to be slow?! that’s where most of the time is spent. the problem is that m can be arbitrarily large, and putting a large constant of let’s say 1000 on top of n will make matching 1000x slower. just not acceptable for real workloads, the benchmarks speak for themselves here.

Important Routing Notes
Studio Display and Studio Display XDR were built with the environment in mind, and bring Apple even closer to reaching its ambitious plan to be carbon neutral across its entire footprint by 2030. Both are made with recycled content, including 100 percent recycled aluminum in the stand and 80 percent recycled glass in the standard glass option. Studio Display and Studio Display XDR are designed to be durable, repairable, and also offer industry-leading software support, while meeting Apple’s high standards for energy efficiency and safe chemistry. The paper packaging is 100 percent fiber-based and was designed to collapse so it can be easily recycled.4
Ma said the AI era had arrived faster than many expected and that society was still unprepared for the scale of change it could bring. While the disruption could be profound, he said, it also offers an opportunity for education to return to its core purpose.
