Quite. Much more advanced than in my time, even. It seems more comparable to the era around the turn of the millenium, the year two-thousand, from what I have learned from others who come from around that time. The technology of the domed city beyond the barrier is much higher, however, developed in the hundreds of years since they withdrew-- and the technology from the structure those of us "out of time" all came from is higher, still. That is where your communicator came from.
