My feeling is we're going to have a change similar to what aviation had in 1930-s. Before that we had everything on the ground and sea, and both land and sea transportation were quite developed. The 1930-s, roughly, had a visible birth of the industry of air transportation - more people flew because they needed to get there, not for the thrill of the novelty, and more people worked in the industry - making airplanes, airports, operating them. Similarly, here we so far have less than 1000 people - or so - who flew to space in their lifetime, over last 60+ years. We're going to see it changing in a few years, less than 10, and to see the growth of a whole new industry, which routinely builds stuff for space - be it spaceport-specific equipment, or some hardware for spacecrafts, or hardware intended to work in space. Also we're going to have more professional occupations - hardware designers and hardware manufacturers on Earth, operators of space assets, like fueling stations, orbital stations, constellations, scientific laboratories - manned and automatic - and some orbital manufacturing facilities. And also we'll see professions related closely to the Moon in a few years - since it's going to be cheaper to fly to the Moon, more people are going to go there working on exploration and resource utilization, for lunar and orbital infrastructure. So in our minds today we have "everything anybody does is of course on Earth" with some quite small exceptions for those who flies to orbital stations, or for short tourist flights above the atmosphere (so far, I believe, we never had even 25 people at the same time above 100 km) - and there are, of course, many people on Earth who work exclusively to support such space-bound activities, but it's still more of exception. We'll soon get to the state "some remarkable number of people are working in space, in many different locations and on many different projects", and on Earth a rather large industry supports their activities, just like we have industries supporting sea transportation or automotive industry. We'll get used to add this new dimension into our considerations, our plans, we'll see more opportunities pursued in this area, more attention paid to space - significantly more. Space will become another (much more) routine part of life.
