What happened to Siri??

When did siri get so stupid? It’s so annoying to use anymore. Especially when I’m driving and ask her for directions and she won’t give me directions or she’s giving me options hundreds of miles away. Or when I can’t find my phone and it ignores me.. or if it doesn’t ignore me, it says it’s going to ping my phone but doesn’t. Also, when I ask simple basic questions, it says it doesn’t understand.. it also sometimes gives irrelevant answers. I don’t remember Siri being so stupid in the past. What happened??
