How is it dangerous? Your qualifying remarks with regards to Haskell's domain make no sense. If you need a fast, compiled language with managed memory, high ease of development and a strong ecosystem then you can't go wrong with Haskell.

'Type stable computation' and a strong correctness guarantee are some added benefits of Haskell, though any strongly typed language (like for example Rust) will have these qualities.

A nice benefit of Haskell that most other languages don't have is that it is explicit about side effects which gives you some extra confidence in the behaviors of your code. Related to this is its unusually powerful type system, which allows you to make some abstractions for generic code that are not possible in most other languages.
