I don't really quite get what point you are making here. Are you saying that the innovation today owes more to the innovation of the mid-nineties? Are you saying that any innovation now with respect to AJAX and JS does not make your life better in any way?

Seemingly you argument could be made for cars "15 years ago cars were easy to fix and understand. Now they are not, so wake me up when they are like the cars of the mid-nineties."

JS/Ajax help programmers tremendously. Helps speed. Helps functionality.

To view these things through the lense of "I can't write a crawler for them" is a pretty limited view of what today's technology offers.
