The FAQ for the new Go language explicitly makes this claim:
There is a growing rebellion against cumbersome type systems like those of Java and C++, pushing people towards dynamically typed languages such as Python and JavaScript.
Is there (non-anecdotal) data to actually support such a claim? I've always found dynamic typing sloppy and tiresome, but if I'm losing touch I at least want some warning.
I'd call it a trend, not a rebellion, but I see the same in our company moving from C (25 years ago) over C++(20 years) and java (12 years) to javascript and python (2 years).
One of the reasons could be, that scripting seems to be more agile and better for rapid development (which I actually doubt). That impression came along when some developers started nice applications in impressive development speed, while the 'old OO-family' often came up with (over-)complicated application architectures which showed a depressing progress.
I think it doesn't has to be scripted if time to market is a criterion (but sometimes it helps to get rid of old habits)
