RBS is optional.

[zelly]

It won't be optional in Ruby 4, most likely.

[Daishiman]

Why would you think that? There's no evidence that dynamic typing is going away Type hints are optional precisely because they're not convenient for many cases, and the add-on type systems cannot fully express the capabilities of the language.

[grumple]

Seems unlikely. Ruby is all about options.

[joelbluminator]

Yeah, I second the opinion that this remains optional. Ruby won't become a java-wannabe , that's a fight it cannot and would not want to win. Ruby is dynamic.

I wish I could predict the future with as much certainty as you.
