I’m going to disagree that the ‘sun is setting’ on Rails-style frameworks, however, there is a lot in this to think about: caines.ca: “The Sun is Setting on Rails-style MVC Frameworks”.
There is a circular evolutionary path from thick client, to thin client, to thick client. Are we again moving to an age of thick clients with the browser or smart phone being their host? With the preponderance of so many platforms, I have my doubts, at least in the near-term.
One thing’s for sure — I need to build an application using a fat client just to see what all the hype is about and so I can think about this in an educated fashion.
Rafe, I’m with you there.
