To us it's fundamentally difficult. So far I don't see too much empirical
data that proves it impossible. People didn't think flight was possible.
Same thing with this.

it was just something that came to mind, it's just a generic statement
that other things could be ways of communicating.

i like to keep an open mind. walt disney said , if you can dream it, you
can build it. I try to go by that.

hence the line, serindipity.

back in homer's time, science fiction as you call it was about man flying
with wings and such. It's amazing how no one ever thought that was
possible. Science fiction writers aren't given enough credit.
