My comments were an observation based on what I've seen recently, and none were intended to be a value judgement on any work being done in JS-land. I just don't see a Rails-esque competitor rising from JS land anytime soon and gaining enterprise market share. Cloud has to do with it because Cloud is increasingly how applications are created. Instead of a large framework to create an application with a language (Spring for Java, Rails for Ruby, Django for Python), applications are now mishmashes of cloud functions, no sql tables, sql data stores, message queues and auth wrappers, all of those without a specific language requirement. Like I said in my original comment, it forces every language based framework to question it's (comparatively) monolithic nature. This isn't a fool proof prediction by any means, but with the rise of cloud architectures I really don't foresee any languages birthing a monolith anytime soon. I'm sure lots of folks will use Next.js or something else, and it will be good a tool, but my bet is that even more companies will increasingly utilize the cloud to create less monolithic architectures.
