> I'm wondering if there are plans to replace Java with Dart or Go on the Android platform. There are very few languages choices where I prefer to keep using Java. Go and Dart are two of these. I'm a dedicated Apple skeptic, but Swift is nicer than both of these trainwrecks. If what the article claims is true (that Dart can be used to target µCs), which I highly doubt, it might become interesting for me. My doubts arise from the fact that the standard library for a language makes some opinionated design choices, and in my opinion it's impossible to make an idiomatic library that works the same (and is usable!) in a GC context (existing deployment) and a non-GC context (embedded). It's sad that of the dynamic languages, Python and Ruby are performance deadends, and LuaJIT is too obscure for most people.

Elixir (and the Phoenix web framework) is getting a lot of attention these days from Rubyists who are looking for something that speaks their language that is also fast in realtime distributed environments.

  +1 for Elixir and Erlang VM.

What microcontrollers you have in mind? He mentioned Arduino in the post. It's not like we need Dart for extremely low spec-ed mCs, and we could run GC just fine in higher level mCs for ages...

It's not like we need Dart for extremely low spec-ed mCs The article mentions the Arduino, which in its original incarnation is an extremely tiny AVR. Maybe the author has a more powerful Arduino variant in mind, but I'm pretty sure you cannot run a GC runtime on the AVR Arduino. The only language that runs on such tiny devices is probably eLua. > , and we could run GC just fine in higher level mCs for ages... Yes, RPi/BBB won't have a problem.
