I'm not sure what on earth is driving the sudden spike in Python learning resource searching
It seems SEO for this sort of thing is dead, so another funnel/channel is needed. Also, CS enrollment seems to be down this past fall for the first time in a while (based on the CERP pulse survey).
But maybe there is still a market for that sort of educational content.
I guess they had plenty of time to do such things and some viewers of theirs got inspired and decided to teach themselves Python because it looks easy.
