As with almost any such question, meaning is not inherent in the thing itself, but is given by various people, with no guarantee that anyone will agree.

For at least some people, who subscribe to the information-pattern theory of identity, a whole brain emulation based on their own brains is at least as good a continuation of their own selves as their original brain would have been, and there are certain advantages to existing in the form of software, such as being able to have multiple off-site backups. Others, who may be focused on the risks of Unfriendly AI, may deem WBEs to be the closest that we’ll be able to get to a Friendly AI before an Unfriendly one starts making paperclips. Others may just want to have the technology available to solve certain scientific mysteries with. There are plenty more such points.
