There is surely going to be an increase in more services and a need for experts with these services as time goes on. They are coming out in a rapid pace and with the movement into the cloud for many organizations, adapting these services will be a mouse click away without all the added headaches of purchasing hardware and licensing that many of us faced in the past. Thus, needing to broaden your skill set is going to be in high demand as we progress forward. For example, 5 years ago I was on-prem in the data center and 100% utilizing the Microsoft stack. Today, I'm 90% in the cloud utilizing the Azure stack with other open source technologies to further enhance what I am doing.
Call me cynical, but the more life experience I get, the less I trust very large centralized resources, especially some of the cloud providers, (Amazon, Google). If the cloud is that important, it should be run like a public utility not by near monopolies that are abusive.
