"Uhh, Bruce Schneier is widely recognized as one of the foremost authorities on computer security and cryptography in the world"

His report was fatally tainted when it came out he worked with the CCIA, a Microsoft hating trade group at the time, to produce that report.
The guy and his pals sold their souls to the devil.
That report was trashed right after it came out., when the facts leaked out about the agenda those guys were carrying.

His report was fatally tainted when it came out he worked with the CCIA,

It was a CCIA report, and they asked Bruce to give some input -- I wouldn't say it was his.

Aside from that, if you have ever taken a class in cryptography, you've most likely used his book, "Applied Cryptography." It's just like in a CS degree you will have used Tanenbaum's "Computer Networks" and in an OS design class his book "Operating Systems Design & Implementation."

Schneier is so good, his textbook is the standard.
