I think that's an overstatement.  There were plenty of 8-bit OS-es 
written in assembly.  That Gary did the first version of CP/M using PL/M 
was more a matter of convenience.

In other words, CP/M (if you consider it to be an important innovation) 
would have happened, PL/M or not.  I mean that it's not a lot of 
code--development time would not have been much different.

When DRI tried to foist PL/I on its developer community, that played out 
much less successfully.
