I worked with some of the folks who introduced coding into school districts way back when that movement started, so I have a bit of inside knowledge.

The biggest anecdote I'd share is that learning to code as early as 1st grade unexpectedly led to children taking the ability to troubleshoot problems and using it across all their subjects in school. They started to treat struggles in other classes as debugging assignments: "What went wrong? What do I need to fix?" Their entire attitude changed from pass/fail into optimization. It has led to academic improvements across entire school districts, which was not at all expected but was a delightful surprise.

So the question posed seems fairly irrelevant to me. Maybe some of those kids grew up to be coders, maybe they did not. Either way, it helped their education.
