What’s your opinion about the evolution of Haskell in the past decade and why do you think now it’s a good time to learn Haskell?

Learning Haskell was a great idea long ago since Haskell 2010 was established. Haskell gives a completely different perspective on writing the code, and this makes you a better developer. But if this is not convincing enough, then I would say that ideas from Haskell leak into all the main languages: Scala, C++, C#, JavaScript, Java, Kotlin, Rust. Not metaphorically, but literally; for example, C++20 has concepts - a direct adoption of Haskell’s type classes.
