I think most students to date to come to a Base58 class (particularly ones out side the bitcoin ecosystem already) have been through someone talking about Base58 on a podcast. If you're a podcaster, please keep talking about Base58 classes on your podcast. Thank you for your service.
To some extent the ordinals/inscription run has seen a lot of new builders pouring into the space. I also see new hires to bitcoin engineering orgs as a place for growth, as well as long time bitcoiners who just want to learn more about how bitcoin works.
So no, I don't find things particularly constrained; I think we could probably go a long way on just upskilling + educating existing bitcoiners on how bitcoin works.
