Another question frequently asked about our Ancestors is "Did They have communications like on the popular sci fi t.v. shows; little buttons that you could simply touch and be heard through thousands of miles away?
The answer to this particular question is "No." The average person, or, the average crewmember of a space ship did not have any communications device that small. Every individual carried a pocket com, a small computer that were about the size of a present day cell phone. This computer contained a communications circuit through which all communications were handled, using hyperbands that gave the individual instantaneous contact to any other com anywhere in the world.
Long distance communicators had to be handled through much more sophisticated circuits that had to be stationary.
The commanding officers of warships, however, DID have a small communications device implanted in their skull that gave them instantaneous communication with their ship's computer and through it, communications with the rest of the vessel. But these devices were very expensive, and therefore their use was restricted to military personnel.
No, we didn't have touch communicators, but we still managed to communicate pretty damned well!

Before anybody asks the white supremacist that went on the shooting spree in the Chicago area lasted about two microseconds after entering The Spirit Realm and had a little help getting there. It is too bad that his feeble-minded leader who denies the holocaust and calls non-whites mud races cannot be prosecuted for his crimes. But his hour will come, too. He's being watched, and The Bright Ones are waiting....They're just waiting!
