They never use any low-technology solutions; can you imagine seeing a bucket or a wrench in Star Trek? When their kids go to the beach, they probably take a portable forcefield generator instead of a bucket and shovel. But in real life, engineers don't always use the most advanced technology. In fact, the most elegant engineering solutions are those that require the least technology, not the most. A good example is a machine gun; it uses a simple, elegant and robust mechanical system to eject each cartridge and load the next, based on gas pressure, springs, rods, and other low-tech principles. The simpler, the better. With modern technology, we could design a machine gun that uses miniaturized robotics instead, but why? The resulting weapon would be far more expensive, and far less reliable. It would require a power source, and software. It would be far more difficult to maintain. But in the world of Star Trek, that's exactly how they would do it. In a world where medical isolation bays use forcefields instead of walls, and where dumbbells have touch-screen controls on them, even the dumbest application of excessive technology is not only approved; it's mandatory.
