What’s interesting some of them don’t provide true, material substance, but virtual such as the social network organisations (they make only virtual applications), in some way software development company act in the same way. It is fantastic that people want and make money on product which do not really exist – gis systems. We have a big places to store database which can’t be read without using computer so they exist but unfortunately in some way, the same thing we may say about, for example, very old films with cellulose, but in this case we have got a huge difference: to show an old film we must have a proper apparatus, but it’s a piece of very simple mechanical tool, in case of actual databases we must have software (also advanced technology). In the end we have got branches which disappear or even already completely vanished like shoemaker (this profession is dispace by production firms) or blacksmith (it does exist but just as a artistic branch or as a part of high advanced stables; with racing or pedigree animals), many of them vanish in the nearest future.
Our universe is changing, we develop, create and destroy our reality, no one knows in which direction goes the path of the human fate, but we must be aware of the results of our actions and impact on natural world.
