This routinely happens for professional athletes. Don't have any stats, but American professional athletes seem well known for having many children (with many people).

Yup. People want a bit of hedonism. Who doesn't really? And society paints engaging in hedonism as fine in your 20s and evil for parents. Have kids? Goodbye partying. Goodbye hobbies. Goodbye a sense of agency. It doesn't have to be this way, but this is how it is framed both internally and externally.

This absolutely would have sealed it for me. It would still seal it for me now.

Being disabled, and having AI be a risk to the only work I can perform means financial concerns are at the heart of everything. There is simply too much financial risk even without children.
