My daughter and another 14-year-old girl have just hatched a brilliant plan: make #Siri gaslight her users.
As Big Boss of #Apple they would make Siri give people different grades of information and treat them differently depending on how polite they were to Siri. Examples:
"Siri, it's lovely to see you this morning. What will the weather be like today?"
*77 degrees fahrenheit with light clouds and a chance of showers in the evening. You might want to pack an umbrella for your regular evening walk."
- or -
"Siri. Weather. Now."
*77 degrees... bitch.*
Importantly, Siri would never admit it insulted users or downgraded their information. This would play out much like the ongoing "is my phone listening to me?" question. Also, in transcripts of Siri's messages the insults would never appear. Siri could insult people (which would be very occsaional) in a different voice, so it would be easy for Apple to insist that any recordings of this were faked.
These kids don't have much technical know-how (I think they can maybe code simple things in a kid-friendly scripting language), but their villain skills are top notch.
