No, they are NOT the same EXACT thing. Unity purchased the existing Bolt package from Ludiq last year. This Bolt package is still available for free now to use with Unity 2020 and older. Unity has been directly integrating Visual Scripting into versions of Unity 2021+. As such they are upgrading VS along the way. So, while the visual scripting in Unity2021 (and up) is VERY similar to the older Bolt package, they are no longer exactly the same.
