I am at a similar level / write a lot of Ruby. I have pretty mixed feelings. I do enjoy writing Ruby and echo the low friction between an idea and running code.

However, on very large Ruby projects I have inherited I do see a common flaw of a large (often insane) amount of exceptions being thrown due to type errors. Undefined method blah on nil class. Some of these apps have had 100s of developers working on them of various skill levels. For mission critical code paths I am often the biggest proponent of Sorbet.

While my personal projects involve heavy use of meta programming and taking advantage of duck typing, I have altered my writing style and opinions for large projects.

Part of my frustration with Ruby type system could be explained by the fact great Ruby developers are becoming pretty hard to come by and I have often had to work with developers who are picking it up.
