The arsenic thing was misinformation. It was reported before it had been fully investigated and was debunked as not the case. Carbon-based life is likely the most probable in the universe. Carbon is the most chemically active element in existence capable of more combinations of molecules than combining all possible combinations of molecules of all other elements.

Also we as human beings are made of the most abundant stuff in the universe. The periodic table of the elements is not just a table of complexity, but starting with hydrogen and working through the table is also a record of the abundances of other elements in the universe. We're composed of the most common elements nature has to provide (except chemically-inert helium) in the same 1:1 ratio as the universe's abundances of elements.

As far as space travel to the stars and far-flung colonization goes, I'd say it's more likely that biology is the beginning of intelligent life and that we'll be something technological in the far distant future, shedding the biological ancestry.
