Skills are not only formed in formal education, but many people find skills outside formal education, but back again as we said at the beginning, that education is a person's first step to understand technology and others, with education people will focus more on research and development of new technology
I think it is a very natural thing when there are some people who have other skills outside the formal education they have attended in school or lectures. But some of the people I saw at my place actually went through that education just to get a diploma and wanted everyone to admit that they already had a certain title, but they didn't have any skills at all. And I think this is a very strange thing because after several years of education, they still can't do anything and are not even productive enough for themselves.
