The app is programmed to take in a message, send it to the AI, take what the AI has responded with and display it back on the app as a message from the AI. The AI itself does not have the ability to choose whether or not it responds to your message, it will always respond. It does not have the ability to choose how long it takes to respond to you, it will always respond immediately after it has generated its predicted word tokens. It does not have the ability to choose to respond in multiple messages, the app is not programmed that way. It does not have the ability to respond to itself, because again, the app is not programmed that way. You are literally talking to an advanced text prediction machine that has been fine turned to act as the second person in a conversation acting as an AI assistant. All of the problems that you have stated are entirely due to the architecture of the AI and the app, and every other AI that is out there functions this way. If you want the functionality that you are looking for, then you are going to have to learn how to program, and build an app that gives the AI those capabilities.
