Really, what do I sell as my expertise Florian? Have you seen me claim expert knowledge of Java?

1. I tested this on the latest long term stable release of the JDK that I could download. Worked fine.

2. Java was designed for a very specific usage: Consumer electronic devices. Go was designed for broader usage. If you could use a language made for electronic gizmos for the enterprise, then sure you can use Go.

Florian you evidently don't know how technology works. Languages get developed for all sorts of reasons, but because programming languages are general purpose then can find all sort of alternative uses.

Lua was designed as a data description language but ended up getting used mostly for scripting games.

Python was definitely not designed to be a Machine Learning langauge but that is a bit part of what it is being for today.

JavaScript was most definitely not intended for the broad usage and the size of applications it is being used for today.

So no, most languages don't have a really narrow domain. Most languages can be used quite broadly if you really want to.

My article made it pretty clear that I had Googled basic Java code examples. If you drew the conclusion that I was passing myself of as Java expert, then there is frankly something off with your deductive powers.
