Why We Switched from Python to Go
Nick Parsons

This sounds to me more like a commercial for me than user experience examples. Nobody would change to another language because “…the feed infrastructure for 500 companies and more than 200 million end users…”. I do not care how much people is using it, as long as it is working perfect for me. If in my case a language does the trick, why do I need to change?.

I was expecting more than type of examples, not the type of explanation you read when you go to the language site.
