Native won't die.
True, it won't - all frontend frameworks we've seen so far have been a fad, some longer than others.
I liked the article overall but strongly disagree with your comment on Xamarin. Xamarin in my opinion offers the best of all the cross platform dev platforms. If you like the flutter approach, take that in Xamarin using Skia or use the amazing Xamarin Forms or even go fully native with better tooling! I think the biggest advantage with Xamarin is the huge collection of pre built packages already built for you!
