This is a hard problem, because it involves mindshare and resources; even a perfect language would take years to gain a serious foothold. But it'll never be solved if nobody tries.
This is definitely true, and the exact point I'm building my arguments upon. Are Rust and Go better languages than C and C++ for solving lots of problems, in many, many cases yes! But we can't use them. How frustrating is that!?
Of course there's a difference between being able to use a language and when mainstream starts picking it up. Considering for example C++, it wasn't only until mid 90's when it really took off, a bit more than 20 years after it was named C++ from C with Classes. Perhaps Go and Rust have their place in the stack sometime in 2030.
I'm glad someone's trying.
