A recent IRS- and academic-based study found households accrued about $116 trillion in total capital gains from 1954 to 2021, but less than a fifth of that was ever reported on tax returns as a realized gain. The study also found that households had around $16.2 trillion in total capital gains in 2021, which equates to about 94% of net national income and exceeds total wages, dividends, and interest income.
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.
