I&#x27;m seeing a lot of complaints about Crystal&#x27;s slow compile speed.<p>But isn&#x27;t Rust&#x27;s compile speed also slow too and it&#x27;s still being used by many engineers?<p>Even then after 1.0 for Rust, I haven&#x27;t seen any compile speed improvements in that space lately.

<p><pre><code> def fibonacci(n : UInt64) return 1_u64 if n &lt;= 1 fib(n - 1) + fib(n - 2) end puts fib(46) </code></pre> Am I reading this wrong or should that start with `def fib(n : UInt64)`?

Do I need to know Ruby in order to better understand Crystal? I&#x27;m interested in learning Crystal, but the community is quite small and the learning resources, sparse. Ruby on the other hand has a massive presence in the form of tutorials, books and blog posts. I have some minor experience with Python, Java and PHP.

Yay finally! Crystal is awesome, with the exception of compile times

Is there a possibility that Crystal could be used on MCUs? What would be its advantages over Micropython, C&#x2F;C++&#x2F;Rust or Zig?

What&#x27;s the niche for Crystal? It seems like Go is the performant and easy, while Rust is the safe, ultra performant but hard. Elixir solves the problem thst Rails is solving in a better way, so it&#x27;s hard to identify a niche at this point.

To me, Ruby syntax&#x2F;semantics look like an incoherent mishmash of bad practices&#x2F;design choices; I wonder why so many people seem to love it to the point of thinking replicating its features is somehow an advantage. I genuinely don&#x27;t understand.
