Things that aren't alive rot.

Entropy eats them away.

Software has not been alive.

When the external life support stops, they rot.

But software with LLMs involved can be alive.

It can be self-maintaining, to make itself forward-compatible, automatically.

As long as the basic runtime it runs on continues working in backward compatible ways, it can continue working in perpetuity, by fixing itself to work even as the environment changes.
