>oh cool, today is the day you get to learn about X.

I still don't like this. There is no need to comment on my knowledge. If I say I don't know something, there is no need to repeat it back to me in any form. Offer resources, assistance, or guidance. If I found something I need to learn, assume that I will now be scrambling to learn it.

The intent of that sentence is not to repeat to you that you don't know something. That's already established.

It's to signal that the other person is not judging you negatively for that fact.

I fully understand the intent, but it doesn't come across that way. Assume that I will learn it, and I will assume you aren't judging me.

If I'm not busy, it is cool. Very cool. But if I have to spend hours reading and experimenting just to get to the next phase of some task, not so much. When I'm working, I like to accomplish things and learning can be a speed bump. I love learning new things during learning times. This also helps the learning process as I'm not facing stressful deadlines.

Stated as is, it also sounds like you are offering me the privilege to get to learn something you already know. I get to join your club. I've even heard people claim responsibility for another's knowledge because they were the first person to mention the topic. Same for TV shows, music, and movies.
