Its honestly not that hard to predict, with a bit of statistics and some insights into early deep learning, its obvious that alot of data with discernable patterns will produce good results.
I understand that the value proposition of Rust is better C++, Deno is better Node. Crystal's "Better Ruby" doesn't sound like much given Ruby is niche anyway. What is it for Nim and Zig?
Zig is a better C in many ways. Memory handling, error handling, security, but most importantly it can be used together with C. No need to port your code base just swap to zig and continue. Of course now you have a code base in zig and C... :/
