What’s interesting some of them don’t provide real, material product, but virtual like the social network companies (they produce only virtual applications), in some kind of way software development company work in the same way. It is fantastic that people want and earn money on product which do not really exist – crm. We have a large spaces to store database which can’t be read without computer so they exist but unfortunately in some kind of way, the same thing we can say about, for example, very old films on cellulose tape, but in this matter we have a huge dissimilarity: to play an old production we kave to have a proper device, but it’s a piece of very easy to construct mechanical tool, in case of current databases we must have software (also advanced technology). In the end we have got branches which disappear or already completely vanished like shoemaker (one work is replace by production organisations) or blacksmith (it does exist but 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 increase, create and destroy our present, 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 influence on environment.
