almost every regex engine today descends from one of two approaches: Thompson’s NFA construction (1968) or backtracking (1994). Thompson-style engines (grep, RE2, Rust’s regex) give you linear-time guarantees but only support the “standard” fragment - | and *. backtracking engines (the rest, 95% chance the one you’re using) give you a mix of advanced features like backreferences, lookarounds.., but are unreliable, and can blow up to exponential time on adversarial inputs, which is a real security concern known as ReDoS. to be more precise, this exponential behavior is not the only problem with backtracking engines - they also handle the OR (|) operator much slower, but let’s try to start with the big picture.

Readers are simply more willing to tolerate a lightspeed jump from belief X to belief Y if the writer himself (a) seems taken aback by it and (b) acts as if they had no say in the matter---as though the situation simply unfolded that way. Which is precisely what the phrase "it turns out" accomplishes, and why it's so useful in circumstances where you don't have any substantive path from X to Y. In that sense it's a kind of handy writerly shortcut or, as pg would probably put it, a hack.
