    Analysis

    This short blog post uses a reference to the TV show "Pluribus" to illustrate the author's conflicted feelings about the data used to train large language models (LLMs). The author draws a parallel between the show's characters being forced to consume Human Derived Protein (HDP) and the ethical compromises made in using potentially problematic or copyrighted data to train AI. While acknowledging the potential downsides, the author seems to suggest that the benefits of LLMs outweigh the ethical concerns, similar to the characters' acceptance of HDP out of necessity. The post highlights the ongoing debate surrounding AI ethics and the trade-offs involved in developing powerful AI systems.

    Given our druthers, would we choose to consume HDP? No. Throughout history, most cultures, though not all, have taken a dim view of anthropophagy. Honestly, we're not that keen on it ourselves. But we're left with little choice.

    Analysis

    This paper presents a novel diffuse-interface model for simulating two-phase flows, incorporating chemotaxis and mass transport. The model is derived from a thermodynamically consistent framework, ensuring physical realism. The authors establish the existence and uniqueness of solutions, including strong solutions for regular initial data, and demonstrate the boundedness of the chemical substance's density, preventing concentration singularities. This work is significant because it provides a robust and well-behaved model for complex fluid dynamics problems, potentially applicable to biological systems and other areas where chemotaxis and mass transport are important.

    The density of the chemical substance stays bounded for all time if its initial datum is bounded. This implies a significant distinction from the classical Keller--Segel system: diffusion driven by the chemical potential gradient can prevent the formation of concentration singularities.
