Self-Service vs Personalized Support

I think we can all agree that customer success is evolving quickly. One topic that has been discussed quite a bit is the idea of self-service or "customer led". 

Candidly, I feel a bit conflicted. 

- As a SaaS buyer/user - I love the idea of a product and resources that I can seamlessly use without having to add more meetings/ trainings to my calendar.

- As a CS/CX leader - this is intriguing but also a bit terrifying.

With the rise of self-service options, how do you maintain a balance between empowering customers to find solutions independently and providing personalized support when needed?
