I understand he said he's at 98% and his wife is at 93% sure, which means there's a fraction of a possibility that someone might say, "Wait!", but I gotta say - everyone saying to someone who doesn't want kids "You might change your mind" can be so terribly annoying. Even if the person is "only" 24.
(By the way, 24 is the same age many people somehow know they want kids, which is rarely, if ever, questioned, and certainly not cautioned with, "Why not give it a few years and make sure you're emotionally prepared for the responsibility and aware - as much as you can be - of how it will impact your life, your marriage, your work, and everything else. You really should be as informed and prepared as possible before introducing, and then raising, a whole new life, and of all things in life to not treat lightly, it's probably having a child.").
No one says these things (not in polite company, anyway) to people who want kids. It's assumed that they "know," even if they say they're only 93% sure.
Why should those who don't want a child be any less trusted to know themselves and what they want? Why is having kids while uncertain (or uninformed or absolutely oblivious) more readily accepted (even encouraged through a lack of skepticism or questioning) than not having kids?
When people don't want kids and they use birth control that's unreliable, what we end up with is unwanted pregnancies that can often lead to abortions or bitter, resentful parents. Doctors who won't allow women or men to get sterilization procedures are deciding FOR them that they must have the option to become pregnant - even if they don't want to (thereby sometimes contributing to that future abortion or unhappy/resentful - and likely divorced - parents).
If someone wants to get sterilized, it almost seems better to encourage them to have the procedure than to not. What's the big harm in not having babies? And why the push to have them? (Highly recommend "The Baby Matrix: Why Freeing our Minds from Outmoded Thinking about Parenthood and Reproduction Will Create a Better World," which addresses pronatalist beliefs and how they pressure people to feel like they *should* want and have children.)
People change their mind about things all the time, and that someone WILL change their mind is never a guarantee. What if someone said to a pregnant couple, "Welp, you know, you might change your mind in ten years, so... Good luck!"?
Erring on the side of not having kids is far more responsible than erring on the side of risking an unwanted pregnancy. As many have said, adoption is an option IF someone changes his/her mind. And if adoption proves to be a problem later, well... we all make our choices. Parents can't suddenly decide to go back in time and not have kids, and sometimes people who didn't want kids when they were younger can't magically make them appear when they're older. Life is choices, so we do the best we can and accept that by the time we die, we will not have had every single thing we ever wanted the exact way, time, and place we wanted it.
I was 27 when I got it. I was 100% sure I never wanted kids and my wife was too. I'd rather be stuck wanting to have kids (and have the option to adopt) than be stuck with a kid that you weren't planning on having. This way, we never have to worry about any surprises again!
