Virtual assistants have long served as popular intermediaries between humans and digital devices, but recent advancements in Autonomous Artificial Intelligence Agents [AAIA] promise to significantly transform the technological and cultural paradigms of human–computer interaction. This progression signifies a shift towards greater autonomy and personalization in AI systems, leading to deeper integration into the fabric of individual lives and societal structures. However, it does not guarantee unequivocal benefits for human and social well-being. The interplay between AAIA and human users raises critical socio-ethical challenges, concerning cognitive outsourcing, rational persuasion, manipulation, undue anthropomorphism, and value misalignment. This paper aims to contribute to developing a theoretical framework to address these pressing ethical concerns and potential adverse consequences. It seeks to lay the groundwork for public discourse and policy deliberation in this emerging field, as well as inform future design and governance practices, thereby promoting more responsible socio-technical approaches in AI.

The aim of this work is the reduction of the throttling noise when the capillary is used as a throttling device. Based on the theory of bubble dynamics, two-phase flow, and aerated supercavitation, four different sizes of aerated devices used in refrigerator refrigeration systems are designed. Throttling noise and the temperature and pressure of inlet and outlet of the capillary are measured under stable operation. To compare the noise suppression effects in different groups of experiments, we introduced the cavitation number to analyze, revealed the principle of aerated supercavitation to suppress noise, and combined the results of Fluent simulations to get the relationship between the noise suppression effect and the aerated quality. The experimental results showed that the aerated device can obviously suppress the throttling noise of the capillary outlet, up to 2.63 dB, which provides a new way for reducing the capillary throttling noise.
