Shader Graph vs Cg

[DevDunk]

Cg/hlsl will always be supported, as shader graph converts to this.
Shader graph is just a visual representation of this for ease of use.
Shader Graph won’t go away anytime soon. Cg/hlsl might be partially replaced with the new block shaders:

Block Shaders: Surface Shaders for SRPs and more (Public Demo Now Available!)

Greetings from the Shader team! We heard your feedback regarding the need for SRP compatible surface shaders, as well as a better way to integrate with Unity’s Shader system, and have been hard at work to provide a meaningful solution which we are now happy to announce in the form of Block Shaders. Block Shaders introduce a streamlined and modular text-based shader authoring workflow, and allow to override and extend the functionality of existing shaders, without the complexity of modifying …
