This is almost the exact opposite of how I determine what tools to use. If it's written in C or Java, I'm usually pretty confident that it is engineered by a team of experienced developers. Both because the languages are technically more difficult to use, and not as cool.

In contrast, if a tool is written with javascript (Node) or Ruby, and often times Python, I'm very hesitant.

In fact, this whole topic of streams has me wondering just how many developers out there are setting up clusters of Kafka or Redis or whatever is new and hip, when they could have saved themselves a huge amount of pain by using tried and true tools like JMS or ZeroMQ.

Most companies do NOT have a need for scaling like Netflix or LinkedIn, and I'm beginning to wonder if Kafka, Redis, etc are this year's version of NoSQL and MongoDB hype.

I should have clarified - web applications in Java, built by web developers, are not to be trusted. ES -usage-, not ES itself, is/was the nightmare before es5 (which is much much much more defensive against anti-patterns).

I love redis, so I certainly don't have issue with code written in C, heh. Just code written in C by junior developers :P
