Using the logic suggested at the beginning of this thread, one wonders why all technologies couldn't simply be integrated into one: a combination weapon, computer/sensor/analysis/recording device, and a telecommunication device, and then just build it into a landing party jumpsuit uniform so the wearer never has to take time reaching for anything. Or, for that matter, why bother exposing landing party members to hazardous survey missions at all; why not simply send an EMPIRE STRIKES BACK-style
Imperial probot droid to do all the dirty work for you?
I suspect that things don't work this way in the STAR TREK Universe because it is explicitly understood that the Milky Way galaxy is still a vast frontier filled with unknowns, hazards, first contacts/diplomatic tigers and security risks that mandate the explorers to follow a few simple rules:
1: field equipment is to be kept simple to meet specific needs. Suitcase nukes are
possible, but you don't expect everyone to carry one in their back pocket. You want field gear to be basically functional, powerful enough to do the job, ingeniously designed to be
customized, but also simple enough to be
serviced in the field where you might be a
long way from any supporting technologies.
2: Automated probes are best used in deep space and then only sparingly. If unfriendlies are lurking nearby, it's probably best not to keep sending out probes filled with your best technology for them to capture. So keep your probes simple and use only a limited number of them. This policy preserves security and the Prime Directive at the same time.
3: Automation is to be used sparingly anyways, lest humans become too reliant upon the jodgement of
machines that could go awry.
I would imagine the Archer probably thought of these policies himself in the early days of the Federation. Can anyone else think of other logical reasons why explorers in the STAR TREK Universe don't use super-high-tech Electrocomp-like super-devices like the ones
ELECTRAWOMAN AND DYNAGIRL used?
