Siri isn't very strong, it can answer (very) basic questions and resorts to web searches when it can't answer. I find it occasionally mishearing me or completely parsing my question incorrectly. I recall a particularly bad one: "set a timer for 3 minutes and 15 seconds" and somehow it interpreted it as an arithmetic question "the answer is 18." Alexa and particularly Google Assistant are much better, the latter retaining context between questions e.g: "who is the 44th president of the US" followed by "who is his wife?" is a neat trick.
