It's way ahead has been for some time. I saw it nearly 13 years ago in my internship and have done primarily .NET stuff in the interim. It's only gotten better with age, dotnet core and new features.

There are gaps - data ecosystem is dominated by Java/Scala/Python. Numerical computing is dominated by Python (used to be R!). Microsoft has a decent story in their own ecosystem for the former. Their work on more numerical data types, generic math, and more are what I think is the start of bringing numerical computing to dotnet.

Can't wait to see what the next 13 years hold.
