No. wouldn’t. And the kids themselves wean themselves off the kids version at about age 6 suddenly by whatever interests them - seems all:zero for all the kids I’m aware of using the kids version. But the greatest impact in my opinion is understanding a structured lesson is a skill they mastered before formal schooling which puts them ahead. Not to mention early use of english - not our mother tongue.

Khan Academy Kids is incredible. Watching a toddler battle brain fatigue learning the number two because they want to is terrible and terrifying. If you let them pace themselves and treat it as a game without forcing a schedule they easily get two years ahead of schedule. But it is so much an outlier.
