I learned programming from C# which has an excellent standard library. Just recently started using Go which seems to have a good standard library. Been using python for years, can't say I ever had a complaint about the standard library.

Rust meanwhile seems to be following some "no standard library" philosophy.

I feel like there's an opportunity out there to become like an amoeba: fund and build a third party Rust standard library, absorb absolutely everyone who is so grateful to have a library, and then get so big absorb Rust itself.
