What’s interesting many of them do not provide real, material substance, but unreal like the social network firms (they create just virtual applications), in some kind of way software development – do sprawdzenia na tej stronie – company work in the same way. It is interesting that people want and make money on product which don’t actually exist – gis systems. We have a great spaces to keep 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, very old films with cellulose, but in this case we have got a huge difference: to play an old production we kave to have a adequate apparatus, but it is a piece of very easy to construct mechanical equipment, in case of actual databases we must have software (as well as high technology). In the end we have branches which disappear or already entirely vanished like shoemaker (this profession is dispace by production corporations) 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 disappear in the future.
Our sociaty is changing, we develop, make and destroy our reality, no one knows in which direction goes the path of humanity, but we have to be aware of the consequences of our decisions and influence on environment.
