As cool as Ruby is as a language, the politics are very strange. As Javascript VM performance starts to become orders of magnitude faster than any Ruby VM, there is less and less reason to invest time writing code in Ruby, particularly with superb syntax options like coffee and cljs, and better and better systems level alternatives (Rust, Swift, Go, etc... ) Ruby/Sinatra used to be my favorite combo, but since Rails started going off in a weird direction (anti-js, asset pipeline, choosing AR over DM, insecure defaults pre rails 4) there has been less good stuff written in Ruby to draw from to augment Sinatra... Rails has become a rapidly changing but rarely improving API. That Ruby 2.2 breaks Rails 3.2 is just one more reason to look elsewhere. I question why anyone would start a new project using Ruby at all. This is not a troll, I really don't think there are significant benefits anymore.

Of course it's very much a subject for debate, but I personally don't know a web development platform that is as fast to get off the ground and as complete as Rails. Some people are certainly trying, but I don't think anyone beats Rails in these two areas yet. You specifically mentioned starting a new project. I think that's where Ruby and Rails are the strongest. Maintaining a large system might be better done using some other language and framework.

  I personally don't know a web development platform that is as fast to get off the ground and as complete as Rails I think this is an aesthetic preference. I personally think that the simplest and cleanest design is a combination of something like Sinatra/Express to implement a simple API and React on the client to do component-ized UI. Much of the "completeness" of rails is simply not needed when client side components can keep a bit of state around for housekeeping and make the occasional API call when data actually needs to move between client and server.

    Not every new project is a SPA. It's completely possible to start a new project in 2015, which basically is a WEB SITE (with mobile views and everything, but basically a poor old website), in this case Rails is still the best option.

      You mean with server rendered HTML? IMHO the component abstraction provided by something like react leads to much cleaner separation of concerns, better boundaries between parts of the system, and easier to change/understand code.

You make it sound like speed is the only purpose of a programming language. If that was true. we'd all be writing C. Ruby optimizes for programmer happiness - that was Matz's explicit goal when writing the language. If that doesn't matter to you as much as speed on microbenchmarks, or if writing Ruby doesn't make you happy (it makes me happy!) then Ruby isn't for you.

  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.

    I think there's a huge misconception that to scale your programming language must be concurrent and also extremely fast. I can't see how you can assert that the JS ecosystem is "better". It is rapidly changing which is partially detrimental. What worked or was considered a good choice at the start of 2014 is now mostly obsolete or abandoned by the end of 2014. As so many companies have shown it really does not matter what programming language you use as there are plenty of options to make it work, it's more about choosing the language that will provide the best fit for your business.

> I question why anyone would start a new project using Ruby at all. This is not a troll, I really don't think there are significant benefits anymore. One might start a new project with Ruby if it were one's primary language, and there was a desire to build something without the overhead of working in another language in which one is less proficient. How about this analogy: there are many different ways to cook a meal, but often my goal is to prepare food easily and quickly so I can eat and move on. Thus, I usually stick to the relatively few methods with which I am comfortable. Sometimes I do experiment with the goal of learning something new. But in those cases, the primary goal is expanding my skills, not building the "product" as it were. edit: clarification

  Quite true, but over time that erodes as a good reason. For people for whom the learning curve of a new framework/language is minimal there are fewer reasons to use anything in the Ruby ecosystem these days (I think).
