Trolling or not, comment is unproductive. Might I suggest offering alternatives such as rehashing the "rust is arguably a better design with similar goals" vs "rust's library isn't as complete and the language isn't stable" debate?
I have been writing Go code professionally nearly every day for 6 months. Would I rather be writing C? Probably. Python? Not on a project of this scale. C++? Toss up. Java? No - doing far to much interfacing to C libs for that. Rust? Probably. Go is far from perfect, but honestly not that bad.
Comparing Rust to Go is equally unproductive, given that they target wildly different use cases and embody dramatically different philosophies. You might as well compare Lua to Objective-C, or OCaml to Malebolge.
It can be learned by a programmer knowing only imperative C-family languages in a couple of hours, meaning I can hire any average developer and make him productive in less than a week. Not the same as teaching pure functional style with pattern-matching and prolog's syntax. Go is also much more efficient. It also produces static executables and can be easier to deploy -- or not, depending on the exact situation. It handles strings nicely -- anything other than Erlang's approach to strings is nice.
Erlang has other advantages, though. 99.9999999% uptime and hot code replacement are easier with it, for instance. Their ideal niches don't completely overlap.
I don't know much about Factor, it's a Forth implementation right? Just inspired by Forth?
Either way, the example[0] I was greeted with on the homepage[1] is quite awesome. Does it have an actor implementation like Erlang? How does it handle concurrency?
