This example just annoys me. I can still out-create a toddler, that isn't hard. The issue with creativity is that toddler-level creativity isn't useful. The important part of creativity is being able to apply it while achieving adult-level goals.
The article doesn't ignore that as such, but this is like saying babies can handle the concept of abstract variables so we can all be programmers. True enough, but not at all a useful observation and it'll just depress the group of people who, for whatever reason, struggle hard and yet never become programmers. There are minimum standards that toddlers do not reach.
