When the number of internet exchanges/NAPs/MAEs started to grow in the
early/mid 1990s, many people expected this to be a temporary phenomenon:
surely, broadband ISDN would obsolete them.

This hasn't happened. However, the reasoning still stands: why buy rack
space in a remote place and go through all kinds of trouble to install a
router there, if you can easily use some kind of switched/multiplexed
service from a telco and directly connect with your intended peering
partners over it, regardless of where everyone is located. (Hey, does this
sound like private interconnects?)

This may still happen as ethernet becomes telco-friendlier. But as long as
you're in a location anyway, interconnecting with other networks who are
there as well is always cheaper and easier.
