This question originally appeared on Quora: How can I minimize my chances of having a disabled child? Answer by Matthew Might, professor of computer science, medicine.
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?
Let me be clear — I’d trade away all my accomplishments, titles and degrees in a heartbeat and with no regret if it would cure my son:
I am not advocating that you run off to stick your testicles in a microwave in a desperate bid to repeat my feats in life.
Eight years ago, my wife and I did the standard prenatal screens.
They came back normal, and the pregnancy was largely uneventful.
Shortly after I finished my Ph.D. in computer science and my wife got her M.B.A., our son Bertrand was born. A few months later, I started a tenure-track professorship in computer science at Utah.
At six months old, we realized something wasn’t quite right. An odyssey began.
Three years ago, I wrote a long blog post describing that odyssey, and its improbable conclusion. Here’s the CliffNotes version:
More things happened:
Meanwhile, as a computer scientist during all of that, I made discoveries like parsing with derivatives and abstracting abstract machines, and even how to do deletion in fundamental data structures like persistent red-black trees.
I’ve published 45 papers. I picked up three DARPA projects, four NSF projects and two DoE projects aimed at everything from next-generation cybersecurity to cancer-fighting medical robotics to exascale scientific computing.
Yes — all while having a disabled son (and clearly an amazing wife [see below] to make all of that possible).
Moreover, I attribute my success in computer science to my son too.
My son forced me to systematically examine what matters in life — what really matters — and in the end, I came to appreciate a quote from his namesake, Bertrand Russell, more than I could have ever imagined:
“The good life is one inspired by love and guided by knowledge.”
My first year as a tenure-track professor cannot be described as anything other than an abject failure. I was so desperate to publish and raise funds that I began thin-slicing my research and submitting lots of poor quality papers and grant proposals.
I must have had a dozen rejections in a row that year. It sucked.
I remember huddling on the porch at the end of that year with my wife, telling her, “Well, I’ll at least have a job for six more years.”
I looked at my young son, cuddled in her arms. I saw his very existence hung in the balance between knowledge and ignorance.
Then it hit me: Life is too precious and too fleeting to waste my time on bullshit like tenure. I didn’t become a professor to get tenure. I became a professor to make the world better through science. From this day forward, I will spend my time on problems and solutions that will matter. I will make a difference.
I stopped working on problems for the sole purpose of notching up a publication. I shifted gears to cybersecurity. I found a project on cancer in the med school. I joined a project in chemical engineering using super-computing to fight global warming.
Suddenly, my papers started getting accepted.
My grant proposals started getting funded.
I also started blogging a lot. Blogging, much like answering questions on Quora, doesn’t count for tenure at all, and in fact I was cautioned against doing it, since it was “a waste of time.”
But, blogging became a way to reach out to the world and to transmit technical knowledge, which is what academic publications are supposed to do — but don’t.
Before I knew it, my blog began attracting top-notch students to my lab.
Today, my lab is a team of talented grads, undergrads, postdocs and research scientists. I’m proud of each of them. I can’t imagine it would be that way without my “waste of time” blog.
(I also can’t imagine having published 45 papers without them!)
In the end, I achieved a self-reinforcing sense of fulfillment in my work: because I was proud of what I was doing, I wanted to do more of it.
I am grateful to my “disabled child” for teaching me one of life’s most valuable lessons: the importance of using our hauntingly brief time on this planet to do the things that matter, the things that will make a difference — the things that are inspired by love and guided by knowledge.
So, if you love your spouse and you want to have kids, then have kids.
Accept the inherent risks, and if the improbable should happen, don’t use it as an excuse to not have a strong career in computer science or medicine.
Or both.
My keynote from Harvard’s recent precision medicine conference, describing some of this in more detail, is online:
What my wife has been up to — there’s a reason I’m only half-joking when I call her the “Mother of Dragons”:
I don’t know how she’s able to do it all and be such an amazing mother to our three kids at the same time.

In fact, she’s up to a lot more, but I’m already exhausted thinking about it.
