I have a very tech savvy friend like that. He is aware of the eavesdropping that Alexa does, but he says he’s not concerned as he doesn’t do or say anything incriminating. Yet he admits that when he wants to have a private conversation with his wife, he “takes it outside”. But he likes the convenience of remote controls and intercom features at his ranch. Sheesh!
It would be a wonderful system if it was offline, with local speech recognition and a local server for it’s operation. But the way things are going, someone would likely try to make it illegal to have your own private ‘in house’ system that the government couldn’t monitor.
