botanical definitions of the word "tree" as you want but it will
just be a word defined by other words that are themselves defined
by yet more words that are.... If you tried to dig for meaning
all you'd find is a endless loop, it would just be a game where
words are manipulated according to the rules of botany until
somebody forgot about definitions and pointed to the ASCII string
"t-r-e-e" and then pointed to a large photosynthesizing organism
made largely of cellulose that exists in the physical world. Then
even a martian would notice a correspondence between this game of
manipulating symbols called "botany" that humans had invented and
the way these large photosynthesizing organism made largely of
cellulose live.

trees of the ordinary physical world do not connect with anything
outside this world either in order to have semantic content. A
virtual world would be no different in this respect. The point is
that the content comes from something other formal symbol
manipulation -- things such as pointing and sensory responses.
There has to be something other than the consciousness with which
the consciousness can interact.
I take it you've never played video games.
Not with any regularity. But I take it that when you play such
games, you interact with the simulated environment via the
provided interface -- the game only interacts with itself in so
far as the original programmers designed it to. The semantic
content is provided from outside in either case.
So what do you think would happen if an AI, or uploaded mind were
uploaded into a virtual reality that was fully disconnected from the
physical world? Would that mind no longer be conscious?
Difficult to tell because, by construction, you can't ask it. But if
both the AI and the VR are programmed by some external intelligence,
semantic content might be provided in that way.
