If they do not currently have the view that we're in an alignment-is-hard world, they should explain why and what would update them, and if they accept that view, they should make explicit claims about how they have tried to "sound the alarm" or "halt AI progress", as they committed to doing, or what specific criteria they have for deciding to do so.
a very common use case for regexes is to find matches that are preceded or followed by some context. a classical example being all lines that end with ‘a’. this requirement is usually expressed with a lookahead, where upon finding an ‘a’, you look ahead to check if it’s the end of the line. in a backtracking engine, this is very easy to implement - you just duct-tape the logic that checks the next character, but in a DFA-based engine, this is impossible because you cannot report “the match is here” if the next character is not even known yet. and by the time you know the next character, the position information is lost, so you can’t report the match retroactively (well, unless the distance is fixed of course..).，更多细节参见体育直播
