"SCADA started off with archaic protocols such as FDDI, Token Ring but “good luck building a network with anything other than TCP/IP now,” Lakhani added."
Uh, last time I looked, Token Ring was a transport protocol, it can handle TCP/IP traffic just as it can handle any other.
True, it's expensive and outdated, but goofs like this make me wonder whether anything the guy says can be trusted.
