The downvote without any whatsoever explanation is just the confirmation that nowadays the different languages/technologies are picked up mainly because of fanboysm/cargo cult rather than because they are useful for a very specific problem.
It's easier to pickup whatever other people are choosing for themselves in the same way as it's easier just to press the downvote button without any explanation.
Honestly this social side (upvote/downvote) leaves me quite sad thinking about the endless discussion that were triggered once upon a time and that nowadays are just becoming a war of upvotes/downvotes.
