I know how exhausting it can be. I've been there.
At the same time, it's such a wonderful problem to have.
I'm sure you will look back at this stage with a great sense of fondness one day. I do hear kids grow up, become teenagers, and stop talking to their parents about a lot of things.
That aside, when your DS finds his true love, just about everything else might disappear into the background. He'll probably be still curious about other things and learn about a lot of tops but his intensity will be directed towards his passion and as he gets older, he'll get more independent about learning.
I actually miss the way how DD was. Yes it really was very time-consuming but I loved being her learning guide. As I am not a STEM person, it was quite educational for me as well.
