Is it fair to assume that parents will eventually become obsolete?

This article got me to thinking.

It seems that increasingly, when it comes to children, parents are being nudged out of the picture by one busy-body or another.
A note from parent is not an adequate excuse for school absence.
Somebody else teaches kids how to drive.
Somebody else teaches kids sex ed
Somebody else decides if proper medical treatment is being given to the kids
No parental consent required for birth control pills or abortion.
(NOTE: The post is not about abortion. I don’t care who gets abortions or why.)
In fact, now that I think about it, parents don’t even need to have each other to be parents.
And now, this article.
All over the world, there are good parents and bad ones.
I guess, because of the fact that there are some bad ones, somebody decided that all parents, good or bad, are simply not up to the task. If the trend continues, will parents become obsolete?
