is it necessary to attend a formal school these days when there is a lot to learn from elsewhere?

Answer 1

yes. I used to think otherwise, but big companies still prefer people with higher degrees. You can get jobs with skills you acquire from some where else, but when it is time for promotion, your co worker with advanced degree will get it.

Answer 2

Formal schooling is not necessarily the only road towards education. It is, in most countries required by law up to a certain age. There is a wide variety of school choices, depending on where one lives. Certain core subjects are necessary for getting a diploma which is required for most jobs. There is a lot to learn all over, even in school. school itself makes the learning process a bit more organized and effective. It would, for instance be quite challenging to learn to read and to speak, or write on one's own.

Answer 3

the best way to do it is to get the education, then learn from "elsewhere" on the job experience is priceless, but you have to get the job first
