By your definition, a commbadge isn't really practical for everyday people to use because of the "privacy issue." They're better off sticking to Bluetooth and cellphones because they're afraid of being overheard by someone.
Evans:
The combadge in Star Trek could be...
1. Used like the people who use the Next Tel Walkie Talkie feature (usually these people are certain business folk or overly sociable people who are open in their conversations) (
These people are not the majority).
2. Used in combination with blue tooth technology (like an ear piece, wrist watch, ECT).
3. Used as if it was a cone of silence (if such a thing is even possible or will ever come to pass). And even if such technology is in development. It is still not how the the combadge was used on Star Trek.
And the point I'm trying to make is that that you see people everyday having conversations in public with cellphones and Bluetooth period. I see people in public every day too and I'm often bombarded with people having cellphone or Bluetooth conversations around me. Whether or not you can hear the other person is irrelevant, IMO, because you're still hearing part of the conversation. Indeed, at times it's not even necessary for me to hear the other person because of the way they're carrying on.
Yes. But these people today have always had the option to share the other person's conversation (by using the intercom feature on their old phone or upgrading to a cell phone to do the same) and I have never seen the majority of people indulge in this type of behavior.
Also, I am looking at the past (and the present) as a way of looking at what people are going to do in the future. And so far I just don't see people everywhere using two way conversation phone technology as you describe it (as a way of it happening in the future).
Sure, people openly have conversations in public on their cell phones. But they figure you are only hearing part of the conversation so it isn't a complete invasion of their privacy. They also don't feel invaded because they know you can't hear the other person on the other end of the line (i.e. the person in the conversation that they cannot control "in regards to what they say"). The thing is that they CAN control what comes out of their own mouth. But they CANNOT control the other person they are talking to. So most people talk by using a cell phone as it is normally used. So it is not an invasion of their privacy because they control in "what you hear" in that conversation.
Now, of course there are going to be people who forget they are on a cell phone and say things that they shouldn't. But these same people still don't want you to hear the other person on the opposite end of the phone, though.
That's the one thing I agree on, "man." People will do what they will and not everyone feels the same way about things.
Yes. There are going to be people who will use the combadge just like it is used on Star Trek. But they will be in the minority. Just like the folks who use the Next Tel walkie talkie feature (or it's equivalent) and people who use the intercom feature on their home phone are in the minority.
If you look back in history... you will notice most people don't want you to hear the conversation of the other person on the other end.
And using history to tell the future is a simple basic concept of Futurology...
