Grady Hillhouse of Practical Engineering. He provides so much insight to the constructed world around us and, more recently, has done a ton of work to digest complex reports to, as he puts it, "elevate the discussion" around manmade disasters so that the layman can have a more informed opinion.

Pannenkoek as well. He's pretty niche, making videos almost exclusively about Mario 64, but he has an incredible talent for teaching complex technical concepts in an understandable way. It's often really hard for people that freakin smart to turn around and explain their knowledge to a layman, but Pannen puts a ton of work into visuals and examples to make sense of some really comprehensive stuff.

Rebecca Sugar, creator of Steven Universe. They've always had a mission to reach queer kids and have taken inspiration from Mr. Rogers to help children love and accept themselves. Over the course of their career, they've really come out of their shell and fought for representation in cartoons, driving the whole medium forward while supporting their peers across the animation industry. They've been pretty quiet online since the end of Steven Universe, but it's because they're out there in person at LGBTQ+ youth centers teaching kids how to understand and express themselves. I didn't know what it meant to have a role model until I started following their career.
