Seriously, the kernel averages about 200-250 new contributors every release (i.e. every 2 1/2 months). We are not starved for new contributors at the moment at all, do you think we are somehow not attracting new developers compared to other open source projects?
I was mainly referring to something I read many years ago (regarding new kernel devs), e.g., this from 2013 [0]. However, from your response, looks like that's not a problem.

I’m not sure that _this_ is the (a?) problem, but if someone were purely sourcing CNCF / Linux foundation / press releases they might think the project is heading for a day when the old guard keels over and we’re left high and dry.
