I really like Ruby syntax, but lately others are catching up. Swift and Coffee are both (IMHO) strongly Ruby inspired and in some ways better.

Consider how many heroku dynos are dedicated to running slow, non-concurrent Ruby web processes, and how many Kilowatt Hours are burned waiting for Rails to apps to start. These are just not problems people need to deal with anymore.

So while I am a big fan of Ruby (I still think it's the closest to my brain's own pseudocode of any language I've used) the ecosystem is lagging significantly these days, not because it's not improving, but because js is improving at a must faster clip.
