I don't know - i'm 33 ~ now - recently with AI learning is much easier - don't get me wrong I definitely won't say that the brain does not slow down - but I'd definitely argue that we have advantages over kids - be it discipline, knowing how to learn ; and stuff like that - for example let's take coq which is I suppose one of the hardest thing we can learn - you can decompose it in ways myself as a kid or as a 20yo wouldn't even be able to. What I mean is that there is a lot of complexities or stuff i would get stuck upon that I just fly over today and know I'm alright - much better ability to focus in a sense

I learned coq as a teenager because the name was funny and one defined everything in terms of the `succ` function.

Never underestimate our motivation.
