Agreed. FWIW, I support two creators on Patreon:

Professor Leonard, and 3blue1brown.

Both are great if you are interested in learning math.

I can't recommend 3Blue1Brown enough. I essentially had to learn linear algebra three times between high school and college, and his Essence of Linear Algebra series still managed to teach me new things. What particularly sets him apart is his phenomenal visualizations of tricky problems involving higher dimensions, mappings, and the like.

His videos on neural networks are also great. Current Patreon supporter too! My t-shirt is in the mail ;)

I second that. The effort that goes into the visualisations are great.
