You are correct on some points. 32 bit was broken, realtime is a non-feature. It does (by design) lack generics and meta programming (Pike talked about these at length at one point).

I have to disagree on the concurrency model, I think message passing channels are a much more natural primitive to model concurrency in, and goroutines are exceptionally light.

EDIT: When you talk about nimrod, you might go ahead and mention you are the designer of nimrod... it might color your judgement.
