I like it!
You're looking more natural on camera than ever before. I have no idea how youtube algorithms work most of the time, but I hope these can catch on.
I like that you're covering the science stuff, and connecting the dots with the colloquialisms that show up on these boards. Beyond just educating people, it also helps avoid the slippery slope into "bro science", and I am sure that will be helpful for a lot of people.
Also, I noticed the ring. Maybe it is old news, but congratulations regardless!
