How important is this for the future? can a coin like NEO or Stratis take over Ethereum one day because of this?
I dont think NEO or STRAT is going to 'take over' ETH, but they can be good competitors, specially NEO as it can work on all programing languages whereas STRAT is limited to C#. Also, C# is not the 'super-duper' of coding languages.
Isn't C# like coding for dummies? lol
Definitely not for dummies, C# is basically the same as JAVA. C# is however more focused on the Microsoft stack running on windows, however JAVA more Linux/Open source.
C# is considered a low level language, while Java is a bit higher. Java doesn't compile to full machine code and has to be run in a JVM. Java doesn't have anything to do with Linux and open source. Java is cross platform, but it's easy to decompile, whole C# is almost impossible to decompiler.
