Had a similar experience.

Typed languages are great for systems development, and I think, not so good for writing web applications.

I also think, Ruby, Python, JS have dominated web dev world largely cause they don't come in the way of the developer having to constantly convert HTML (untyped) and JS (untyped)into types for the backend programming language.

Remember how ActiveRecord (not sure about SQLAlchemy) simply took away the pain of managing types? You didn't have to explicitly parse or cast "0.001" into 0.01.

ActiveRecord is parsing those types, you just don't do it explicitly. IME, a dynamic language may not get in your way when you need to go between JS and the backend, but it also certainly won't get in your way when you're about to shoot yourself in the foot in a large-ish project with errors that could've been caught at compile.
