My partner and I have 5 kids under 7yrs old -- four of whom are adopted and two of whom are struggling with severe developmental delays (and likely autism, still waiting on formal diagnosis).
When kids get older, they get a lot more "fun" and a lot less immediate work. I can take my eldest two out pretty much anywhere without a ton of effort, they are fun to hang out with, they can be trusted to be kind and respectful in adult spaces, and they'll invite me into kids spaces, etc.
But also, anything can happen. Anything can happen. Your kids could be born with lifelong conditions or issues. They could be healthy at young ages, but develop special conditions as they hit early childhood or late adolescence. They could struggle with lifestyle issues (violence, drugs, alcohol, crime, etc). You may just end up not liking them very much (you may end up wishing they were more like you, when they aren't), they may have hobbies that differ from you, they may choose careers you'd prefer not, they may choose religious views you disagree with, they may end up being LGBTQIA+ even if you aren't, and so on. We have one child who is at high risk of never developing cognitively enough to safely live on their own as an adult -- anything can happen.
Having a child is a literal forever commitment -- even more so than any marriage is -- to love and care for a person that might not even exist yet, no matter who they end up being. Be absolutely ready to make a literal lifetime commitment to love and care for this child as a fellow human, before deciding to have one.
There is absolutely nothing wrong with opting out of all of that, and spending your 20's, 30's or lifetime doing something else -- having a child is a huge responsibility, and not something anyone should ever get pressured into, or jump into capriciously.
