"Silicon based life" is a perennial sci-fi trope - I guess because silicon and carbon share similar-ish valency properties. Has anyone actually tried to flesh out what a silicon chemistry complex enough to support protein analogues would look like? Or more broadly, has anyone proposed schemata for complex, self-replicating chemistries that differ substantially from those we know?
