> Machines aren't part of life.

Imagine an industrial complex. Say, some mining + manufacturing site.

No humans ever go there; it's dangerous, dust everywhere, few places where visitors are even allowed, not designed to accomodate humans, 'nothing' to see or do there.

It's all robotic. The machines run the place, produce their own spare parts, repair themselves, adjust processes as problems come up, improve parts of their own design, etc etc. It's solar powered, the material(s) mined is near-infinite, the whole operation could go on for millenia if left undisturbed. Aaand: the entire complex can produce a copy of itself if more resources are discovered some distance away.

For the sake of argument, would you consider such industrial complex a giant living organism?

No? Alright... let's scale it down 1M:1. Same operation, but the industrial complex doing it, is walnut sized.

Still not "life"? Alright... let's say it largely consists of biological structures ("cyborg"). With some silicon (or whatever) structures included for good measure. Oh, and it moves around according to its own 'will', priorities, 'programmed task' or whatever you call that. If you try to crush it, it'll defend itself or try to escape. If you take half of a rock it's working on, you'll observe it chipping off a piece & move a bit away. Sometimes a # of them will swarm around any intruders / competitors. 'Intelligent', having a will of its own, for all intents & purposes.

You can see where this is going. Something tells me us humans will have to re-visit our definition(s) of "life" @ some point.
