I think the larger misconception he has is that Ruby developers solve the same kinds of problems as .Net developers. They don’t. Not even kinda.... In general, Ruby developers create small to medium size websites ... On the other hand, .Net developers create a lot of large scale enterprise applications.

OK, so what are some of the .NET enterprise applications that are too complex to be built in Ruby - or at least are better built in .NET?

I'm not saying that you can't build large complex applications in Ruby. You can. You could also write them in Brainfuck. Having static typing helps tremendously when you have a team of 50 developers and 15 BAs. There are so many moving parts and edge cases that having an IDE and autocompletion is a must have. A team of 50 ruby devs are going to have a heck of a time keeping track of all of that business functionality without an IDE.

We're on our first steps towards building a new insurance underwriting and policy administration system, with built in rules engine and all that (for an U$ 150 million dollar company).

Why would you think that would be better done in Ruby? (not flamebait, just honest question - never programmed in Ruby)
