Hello @Leroy
At a recent event known as Ignite Kathleen Dollard (Principal Program Manager, .NET) indicated that Microsoft is not dropping VB.NET from the ecosystem. What they are doing is not advancing the language to keep up with C# new features (like in C#9 and onwards) and Blazer.
Although an older post it's worth checking out Microsoft: 'We Do Not Plan to Evolve Visual Basic as a Language'.
And than there is the community of developers which Microsoft listens too like Stackoverflow yearly survey which VB.NET in most cases does not even show up or if it does not very much.
With this said, I'd expect that unless one is building cross platform with Xamarin VB should be a viable language for a long time but than again depending on what is needed VB may fail short and the need to move away from VB might be an option.
If we look back at history to VB Classic, there are still many coders using VB Classic because they can get solutions done while others have moved to VB.NET and another group has moved to C#.
Being a developer means that sometimes change is inevitable and in this case it's dependent on can the selected language get the job done. No matter what developers say about keeping VB.NET in pace with C# is never going to happen, Microsoft cares about developers but we also must understand the bottom line is making a profit.
