I want to go in that direction. But in your definition there are concerning parts:
Why should it be necessarily physical? A Turing Machine can do the job in an abstract space as well.
Why should it be used by an agent for a given purpose? If a living organism is a machine, then the agent itself is the machine.
Got the point?

Following up an interesting exchange, I'd like to ask you:
- how would you define a "machine" broadly speaking?
- is your definition covering a broad spectrum, such as molecular machines, man made machines, computers, etc?
- are you sure that your definition does not lead to defining as "machine" a forest fire or an hurricane?
- which argument would you use to characterize the differences between a molecular machine like kinesin and a mechanical machine like an old watch? Does it work too for a whole cell or the human brain? (at a high level of abstraction, of course)
I have some ideas to share based on universal Turing machines and complexity science, but would like to get more inputs, first.
As usual, I try to bootstrap the discussion by involving a diverse pool of friends and good thinkers: @npub1ary…md4c @npub1nt0…stjf @npub1fr4…q2gy @npub1d0p…un09 @npub1apg…f07c @npub1skv…aky3 @npub1crv…vnx3 @npub1zll…lhfq
