The linked paper is open access: https://www.cambridge.org/core/journals/international-journa...

Among other things, it contains details on what amphiphiles might actually be present on Titan, a very nice set of diagrams explaining their proposed process, and proposals for lab experiments to verify whether the process is possible. I've had a soft spot for the vesicle-first theory of abiogenesis since I first heard of it, so I hope someone runs the experiments. But as far as I can tell, this is all theoretical so far.

amphiphillic vesicles are a stepping stone for persistent molecular forms. essentially a reaction vessel, insulating the contents from the extravesicular mayhem.

It's thought that life on Earth started with RNA mayhem, not with vessels to isolate from it.

RNA world is mainstream, but a few scientists have proposed that something like cell membranes, such as these vesicles, came first and provided the environment for more complex chemistry.

Life exists at the boundaries of density changes.

It makes absolutely no sense that the code would precede the hardware, and the hardware needs shielding.

In defense of RNA: you know about ribozymes, right? https://en.wikipedia.org/wiki/Ribozyme Life does not really respect a code/hardware divide.

The source code of life is recorded and transmitted using physical matter.

Physics very much matters to matter.

For development of any information storage systems made of molecules, there must be a supportive development environment.

To even start the process of doing anything like what we see happening in a cell, homeostasis must be achieved first, and not inelegantly, its not good enough to have a complete cell wall if it has no ports for entry and exit of nutrients and waste product, thats also known as a coffin.

Both the walls and the gates and the information / physical systems to reliably exploit those features must be present at the same time to enable abiogenesis.

Congratulations. Now go and read the literature and learn how this might've occurred. You're not the first person to raise these objections. Biologists aren't morons.
