What’s interesting some of them do not provide true, material product, but unreal like the social ss7 firewall firms (they make just virtual applications), in some way software development company operate in the same way. It is amazing that people want and earn money on product which do not really exist – gis systems. We have a huge spaces to store database which can’t be read without computer therefore they exist but only in some kind of way, the same we may say about, for example, old films with cellulose, but in this matter we have a huge difference: to play an old film we kave to have a adequate device, but it is a piece of quite easy to construct mechanical equipment, in case of current databases we have to have software (as well as advanced technology). In the end we have got branches which disappear or already entirely vanished such as shoemaker (this profession 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 horses), many of them vanish in the nearest future.
Our world is changing, we increase, create and destroy our reality, no one knows in which way goes the pathway of the men’s fate, but we have to be aware of the consequences of our actions and influence on nature.
