I mean, come on, it's 2013...who uses a VHS tape to record anymore?!
remember this is tape was recorded in the PAST. copy ada has been active for many years now. she restarted as a blank slate, but not only did she regain her scientific prowess, she also learned to be adapt with weapons and driving.
also, look at the laboratory where they found the tape. other than the sci fi looking containers and stuff, the door systems, the computers, everything there was old school.

Another "realistic" feature is Derek's indestructible pants and shoes, which are unlike DebOra's sleepwear, not only didn't burn when he was supposed to go into cocoon(and for some reason didn't...), but also were kept intact where as they should have been ripped to pieces when he transformed.
I mean, metal ring from his finger was broken/melted, but not the pants? Now that's what I call the quality x_^
