Is programming become a common knowledge?

Answer 1

I wouldn't say so. Don't be fooled by your own scope - you are most likely naturally looking for or noticing people who are interested in programming. Perhaps there might be more than a year ago and a year before that... but it definitely is NOT a common knowledge.
Algorithmic thinking, in general, is too powerful of a concept for most people I know. And I know a few... :)

Answer 2

yes.....i fully agree......
many people are interested in programming nowadays ......
but intelligent and real programmers are found less

Answer 3

Nothing is closer to truth. Thinking that "everybody" code these days can be very demotivating if you are beginner and also older one...
