I'm sure that within our lifetimes, industry-focused technology will become more and more catered towards the public. Space exploration and underwater navigation will likely become more of an attraction than a tool for scientific discovery. Vehicles like the Tourist Submarine Concept will likely become commonplace at holiday hot spots.
The Tourist Submarine Concept was conceived by Dmitry Pertsula and features a luxurious interior that wouldn't be uncommon on a state of the art ocean liner. I'm sure by the time we are all retirement age, we will have the option to take a trip to the stratosphere or to the darkest depths of the oceans.
