I've read about the possibilities of silicon for decades now, but I've 
never seen details on exactly how it would form the hugely complex 
molecules necessary for life, let alone self-replicate them.

Those are the details I'd like to run by the chemists I know.

Most of the articles I find on quick search say silicon based life _may_ 
be possible, but is highly unlikely.
