No.
Ms.Radia's comments were absolutely correct at the time of her writing, she
just could not say anything that had not happened while she wrote the book.
Tag switching and other proprietary similar technologies, on which MPLS was
built, were faster than IP switching when ip switching was way slower. When
MPLS came out, the speed of ip switching was already greatly improved by new
hardware. So MPLS's design and implementation not focus on beating ip
switching on speed anymore. Traffic engineering, VPN(both cisco and
juniper), integrating ip into ATM and DWDM are the arenas for MPLS, my
opinion.
