Go is much more suited for web apps than any driver or real time performance application; although, I will agree that using Go for command-line tools is great.

Go is much more suited for web apps than any driver or real time performance application; although, I will agree that using Go for command-line tools is great. I haven't used Elixir but as somebody who uses Go, I highly recommend not replacing C/C++ with it unless it isn't performance critical. PS: Go's memory usage is pretty up there some times, another reason you should probably stick with C/C++ in the context mentioned above.
