Sounds like we know different sets of bright engineers. My biases
are that I worked for a Layer 2 switch vendor at the time, and
our IP customers were primarily large ISPs.

ATM is a tool. Some carriers used this tool in 95-97 for line-rate
OC-12 forwarding and TE. Line-rate forwarding at OC-48+ rates
is no longer an issue, and TE is available with MPLS, so ATM is
not a very useful for IP traffic these days. However, TE is
still a necessary tool for some carriers because "they" know it
makes better financial sense for them than adding bandwidth. Your
mileage may vary.
