> They will get bored and invent alternate techniques and want to use 'new' tools to pretty much achieve the same thing. Yup, and plenty of re-invented alternatives will be no better or worse than the tried and true. But occasionally the new tech will be significantly better; that's how tech evolves. The main advantage I expect to get from experimenting with node.js and NoSQL is to be able to take the client-side code that's on the web page (eg instant form validation with javascript, and saving offline to html5 localStorage because the customer wants it to work where they don't have wifi), and re-use it on the server (would rather not have a second codebase in php or ruby-rails to do all the CRUD). With coffeescript I write less boilerplate. And I have to use the latest jQuery-esque plug-ins because the customer also wants touch-screen drag-n-drop functionality. To be sure, there is plenty more interesting things I would rather be learning. But customers don't really care that I might find something else more interesting than their project.
