Moore's law is applied differently to mobile phones, as processing power is less important than battery life. And even if phones will get a lot more powerful, that's secondary to poor bandwidth, a problem that I bet we'll still have 4 years from now.

I use jQuery because it makes Javascript usage sane. Without it I would hate my job.

Have a play with CofffeeScript - perhaps it'll give you enough syntactic sugar that client-side frameworks become unnecessary.

CoffeeScript only takes care of syntax problems. It doesn't handle DOM traversing or other API related issues.
