This self replicating proteins can do a lot of stuff that a program running inside a computer cannot do. Like producing secretions, generate electricity, generate light, generate force etc etc....
They're also way more robust distributed systems. Imagine a compute substrate that was continuously mutating, dying, regenerating, cancering, being polluted by various environmental and self-generated contaminants (e.g. alcohol, adrenaline) yet all the while still able to function as a coherent whole. I think this is sort of the pipe dream of the Internet as a system that is robust under strategic nuclear attack. But us meatbags actually do it.
