I am sure that this is the version David Deutsch endorses.

I submit that "the duplicating kind" arose only from poor word
choice.  I admit that "duplicate" or "to duplicate" carries the
connotation of doubling certain quantites (e.g. runtime, mass,
etc.).  But this was an error:  I doubt if Hugh Everett, for example,
ever entertained the idea that the universe suddenly doubles
in mass every 1/10^100 seconds.
