I actually started to use Rails recently and came from Node and fooled around with Go in a past too. I switched because I found myself to be much more productive with Rails and it's really easy with Rails to do fairly complicated things. The article is jokes because everything he says about performance is irrelevant. You can get a single affordable VPS to kick out about 80 reqs/s with Rails 4 without any difficult caching/craziness on an app that's not super complicated but isn't a basic blog tutorial clone. The same app in Node might perform at 350 reqs/s but who the heck cares? 80 reqs/s is close to 7 MILLION requests a day. How many apps do you have with ~7 million requests a day, and how hard would it be to add a second a server in the mix... wow that's tough. Rails 4 is more than capable of responding with low latency too as long as you cache things responsibly. Fortunately that's brain dead simple with Rails since it handles all of the dirty work for you.
