    The cell isn’t a machine.

    What do you mean by this? I feel like you think the meaning is obvious after everything you’ve said, but it’s not.

    Even if we accept that everything you said is true, all it means is that the cell is a very, very complex machine. More complex than current models account for. It’s just chemistry, after all. The chemicals behave in predictable fashion or else life wouldn’t be possible at all. Molecules moving around, transforming, causing other molecules to transform, etc, etc, to turn food into shit and babies. You can always use the word “machine” to describe that, no matter how complex it is. Just like the word “algorithm” can be used to describe the function of code no matter how complex it is, whether it’s a simple path finding algorithm, or the newest machine learning one.

    But I probably shouldn’t use the word “function” because that implies purpose, and, as you say, no part of the chemistry of life has purpose. I hope you can detect my snark. That’s a pretty lame argument that’s philosophical at best. The purpose of the machinations of the cell is to maintain life and reproduce. No mater how many times you say it, your words won’t change the fact that that is the purpose of the chemistry of life.

    You’ve twisted around the word “purpose” in your head until it has no useful meaning. Nonsense. A molecule can many overlapping, hard to discern purposes. That does not mean it doesn’t have a purpose.
