Space has not changed but technology has, in many cases, improved dramatically. A good example is digital technology where today's cell phones are far more powerful than the computers on the Apollo Command Module and Lunar Module that we used to navigate to the moon and operate all the spacecraft control systems.
I like the aspect of technology. For me to spin the way I do, I would have to carry five crates of records with me everywhere I go, which in this day and age would be like two hundred extra dollars in baggage fees. All I need now is a hard drive and a computer and I can rock anywhere in the world.
If that's there, I believe that technology will probably step up to their part of it.
Technology makes good DJ's better, but also allows your average person to think they're a DJ, and unfortunately there's no checks and balances about people making it a career.
