Sure one should never be technology dependant but learning RnR is a complete different choice than for ex learning J2EE or PHP. These last ones are established and, good or bad, will last for a long time ahead while RnR or similars may already be dead.
You can also have the opposite argument and say : everyone does Java so I want to learn a different stuff so I have a more value on the market. And if by chance the thing I learn is a success I become a guru...till the new RnR "du moment" changes all ;)
I'm on the same position about rich client platform right now : there is this eclipse rcp than I want to learn because of hannover and so on...but AJAX is there...and XUL too...and Macromedia Flex 2 is arriving...and MS also has XALM and... and and and... ;)
