Please define "simply biological machines". I'm not sure "biological machine" had a proper definition. What's machine like about biology exactly?
This needs you to answer some questions:
1. Why do the machine parts in biology show such flexible application? A gear cog won’t ever moonlight as a signaling chip, but in biology you often have molecules doing double and triple duty.
2. How is the biological machine able to build itself? What does self assembly imply for the machines function?
3. Where does this machine get its inner drive? No LLM has been found that starts outputting text unprompted. A car doesn’t decide to move to a shady parking spot. Why? Where in the machine to biological machine continuum does the ability to make internally driven decisions come in? Why does it come in for biology? A bacterium is able to make such agentic decisions unprompted. Why is no manufactured machine able to do this?
"Biological," too, is well defined. It relates to living things and their processes.
> Why do the machine parts in biology show such flexible application?
Evolution.

A gear cog was purpose built for that purpose, but you will find that people often recycle parts into other systems, often in completely different roles.
> How is the biological machine able to build itself?
Protein synthesis.
> What does self assembly imply for the machines function?
The way that a machine is built has no bearing on how the machine functions. I could build the same machine using a 3d printer or a CNC router.
> Where does this machine get its inner drive?
Evolution selected for organisms that survive long enough to reproduce. Different biological systems handle this differently.
> No LLM has been found that starts outputting text unprompted.
If you give an agent a goal, it will perform actions to achieve that goal. This is just as true for artificial agents as it is for biological agents.
> Why is no manufactured machine able to do this?
Many do. Even robotic vacuum cleaners will charge themselves without human prompting.
