▲ 12 ▼ On node.js, go & concurrency

In a recent interview, Ryan Dahl, creator of Node.js, said the following quote when talking about Node's concurrency model:

[...] I think Node is not the best system to build a massive server web. I would use Go for that. And honestly, that’s the reason why I left Node. It was the realization that: oh, actually, this is not the best server-side system ever.

That was strong. Why Dahl, who worked so hard to build and advocate Node.js back then, would just give up his creation and promote something else? What does that mean to Node.js and its huge community?

Let's first do a quick recap.
