I've been hearing that .NET is dead/dying for probably 8 years now. I work on an enterprise software platform comprised of mostly .NET microservices and some NodeJs sprinkled here and there on the back end. 80% of our .NET code is running in a container on a Linux distro. The other 20% just hasn't been ported to .NET Core or has some shitty dependency which can only run on a Windows environment. I see some of our devs switching to Macs for development already. All of this has occurred in just 2 years. I would say give it some time. The progress has been amazing in my opinion.
