That makes no sense, as both machines and organisms can and do have an indefinite amount of external energy and resources supplied. Thermodynamic arguments are really only relevant to 'grey goo', where it is indeed necessary to make a thermodynamic case for why the proposed self-replicators will substantially outperform bacteria.

I hope you are joking... You seriously understand physics this little? A little guiding hint: Every process generates heat, that has to be transferred - whether in a self replicator, or in bacteria. Bacteria solve the problem by a huge amount of redundancy in structures so local heat flow's negative effect on overall performance is lowered. However, this is bad design, as creating redundancy has its own, higher, energy cost. Self-replicators solve the problem by - ignoring the question (They do not transmit information beyond the basic entropic generation limit of the system, so they are cooled by an external substrate, and the researchers pretend the carefully designed substrate just "exists" naturally )

As for your "indefinite external energy": I am not a biologist, but seriously - you do have some inkling of extinction events, famines, natural selection, etc?
As for machines - you do have some inkling of energy crises ?

Organics require food. Food is abundant on Earth.

Machines require appropriate fuel.

Does it take entire paragraphs to state that Bottlestein ? You dont get marks for posting on an internet forum.

^ If you weren't 13 you'd try to understand the content instead of imagining Master Chief while raging at me for calling you out on your bullshit in another thread.

1) "Food is abundant on Earth." Yes very good
"Food" required billions of years to reach an energy density that could support an organism like us in "abundance". Again, given the recurrence of famines and extinction events, your "abundance" is quite clearly bullshit.

2) "Machines need fuel." Let me spell it out in a way you can follow:
Machines need processed fuel. To process the fuel into an usable state requires energy, and produces heat that has to be gotten rid of. This is why, we cannot replace the "abundance" of "food" with the "abundance" of "usable fuel" without massive problems. Try reading this out to yourself...
