The poll was conducted on 8 - 12 year olds (https://theharrispoll.com/lego-group-kicks-off-global-progra...) so I agree that there's time. When I was on the younger end of that range, I wanted to be a garbage collector, probably because it seemed like it'd be great to ride on the back of that big truck. I might have gotten wiser with age.
And at 8, my sister said she wanted to be a rabbit when she grew up. We found the class assignment to prove it when going through our old stuff in the attic.
Now she is a data scientist, which probably didn't exist when that book was written.
I used to say that (from age six) to dissuade further questioning from dull adults. It usually worked.

When my daughter was in 4th or 5th grade they had a "career day" in which students could meet parents who were in jobs they found interesting. I offered to talk with kids about being a software developer. The organizer contacted me the day before to let me know that nobody signed up to talk with me. I was a bit crestfallen. ;-)
At the same age I also became fascinated by computers... and I'm working as a computer programmer.
That said—I might just be further data in support of your exposure theory.
Do you want to spend months at a time in a soda can that can explode at any moment surrounded by vacuum? Or be a modern day bard?

It honestly wasn't until halfway through undergrad that I really got it and decided to actually pursue it
