I feel like if you considered an average developer most people are writing API-like services that talk to a database and a few various APIs, payments, email, notification services, etc. ML is kind of a niche area where Python definitely excels and almost stands alone, but web frameworks are a dime a dozen, and every language pretty much has a postgres or mongo client. "Much of anything complex" probably wouldn't hold true for most developers...I mean, it's all complex given technology, but 99% glue code that can be written in anything. That's generally true for me at least. I have been bitten by lack of libraries for things like Cassandra in the past and switched languages because of it, but that's the exception and not the norm for me, and you really have to choose the right language for some projects. Or have some kind of architecture where you can have different parts in different languages.
