This post from University of Utah Computer Science professor Matt Might is very much worth reading.

Might saw a question on Quora from a 16-year-old who said he wanted to have a successful career in computer science or medicine, but feared getting married and having a disabled child.

Might wrote:

First, your question is trivial to answer: to minimize the risk – to zero – that you’ll have a disabled child, don’t have a child.

Any attempt to have a child will incur risk, although you can take measures described in other answers to lower it.

But, let me tell you a story – my story.

I am the father of a “disabled child,” yet I’m a professor in computer science at the University of Utah, and also currently a professor at the Harvard Medical School.

Hopefully I’ve just dispelled your fear that having a disabled child is not compatible with “a strong career in computer science or medicine.”

In fact, what if I told you that much of what I’ve done was the result of my having a disabled child? Because I too (naively) believe in love, and love my wife and son dearly?
