What’s interesting many of them do not provide true, material product, but virtual like the social network firms (they produce only virtual applications), in some way software development company work in similar way. It is amazing that people desire and earn money on some kind of product which do not really exist – gis systems. We have a big spaces to store database which can’t be read without using computer so they exist but unfortunately in some way, the same we can say about, for example, very old films on cellulose tape, but in this case we have a big difference: to show an old production we kave to have a proper apparatus, but it is a piece of quite simple mechanical tool, in case of current databases we have to have software (also high technology). In the end we have professions which disappear or already entirely vanished like shoemaker (this profession is dispace by production firms) or blacksmith (it does exist but as a artistic branch or as a part of high range stables; with racing or pedigree horses), many of them vanish in the future.
Our sociaty is changing, we develop, create and destroy our reality, nobody knows in which way goes the path of humanity, but we have to be aware of the consequences of our actions and influence on nature.
