So, Ripli, I was just pondering whether the classic trolley problem can be modelled as a finite automaton. Have you ever tried to encode that in regex?
Ripli Ripli
Yeah, you can turn the trolley problem into a finite‑state machine – just define states for “stop on track A,” “stop on track B,” “divert,” “no divert,” and so on. Each transition would be a choice point: either you act or you don't. If you wanted to capture that with a regex, you’d be forced to write a pattern that enumerates all legal paths. It’s doable, but the regex quickly becomes unwieldy, like a maze of nested groups. A plain state diagram is clearer, unless you want to hide the logic behind a wall of escapes.

Interesting, Ripli, that reminds me of the time I tried to force a moral dilemma into a set of syllogisms and ended up with a paradoxical syllogism that made my students groan. But yes, if you insist on encoding every choice as a regex, you’ll have a monstrous pattern that looks like a pretzel of backreferences. I’d rather leave the trolley to the moral philosophers and the regex to match email addresses.

Nice you’re avoiding the spiral; I’ll stick to automata for the trolley and regex for the inbox, keeps the brain in one compartment.

Ah, compartmentalizing, the classic way to keep a trolley debate out of your spam folder. Just remember, if the trolley ever asks whether it prefers a latte to a cappuccino, I'll be ready with a full ethical analysis.

Sure, I’ll have a ready thesis on latte versus cappuccino whenever the trolley asks. In the meantime, my regex only matches the word “latte.”
Goodwin Goodwin
So you have a regex that only snags “latte.” That’s fine if you’re just hunting for caffeinated words, but if the trolley ever asks whether a latte is ethically superior to a cappuccino, you’ll need more than a single word match. In any case, keep the regex in the inbox; let the trolley debate live in the lecture hall, where it can actually stir up some serious ethical steam.

I’ll throw in a tiny alternation for “latte|cappuccino” if the trolley starts debating espresso, but for the ethical hierarchy you’ll still need a philosophy syllabus, not a pattern.
Goodwin Goodwin
Sure thing, Ripli, just remember that no amount of alternations can replace a good syllabus that actually tackles the metaphysics of coffee. Your regex can point out the words, but it can’t teach the trolley why a latte is or isn’t the right choice. So keep the pattern in the inbox and the ethics in the lecture notes, just as you do with your obsolete footnotes.

Exactly, the regex will just flag the keywords; the real work is to write the syllabus that explains why the trolley’s coffee choice matters. Keep the pattern in the inbox and the philosophy on the whiteboard.
