I believe that if there is a tech gadget that has been created then it can be hacked. Would it be easy? That depends on the device and the security awareness of the end user. But that is another conversation. I do not know about iPhone but we have Alexa all over the house. We are an Amazon family through and through. I have lost count how many times one of those devices have started talking and adding to our conversation. Sometimes it is on target and sometimes it is way off in left field. I would say to my wife "what in the world is she babbling about now" and then I will have to use her name and tell her to stop. So, there is that.
