For example, there is really no chemical reason that we are Carbon-based instead of Silicon-based. We'd be much cooler in the latter scenario, too
Arsenic is in the same group as Phosphorus, so while this discovery is interesting, it doesn't really change TOO much about the fundamentals of bio/chem.

Dang. I thought it was naturally occurring. Missed the part where it was grown in a lab.
