Haven’t posted about BBC business daily, but this is a good one: What’s happened to the titans of big tech?

  • Big tech is facing a big moment. With plummeting stock prices, and mass lay-offs, the likes of Google, Twitter and Meta are all – for different reasons – facing some tough questions over how they’re being run. Some see this as primarily a result of post-pandemic blues, the rise in interest rates, and a general cost-of-living crisis affecting the business environment. However, Twitter and Meta especially have seen wholesale desertions by a number of major advertisers, worried about the regulation of hate speech, and therefore by association the safety of brands’ reputations. Does this mark a deeper crisis for the ad-based business model of the major social media platforms? And what can they do about it?


  • Autonomous Weapons: The False Promise of Civilian Protection
    • While developers and users of AWS persist in maintaining the significant role of human operators, a number of questions about the nature of that role remain. Does the human operator simply approve decisions made by the system, possibly distanced by both time and space from the targeting event? Or does the system have the ability to search for targets based on pre-approved target profiles, using sensor inputs to, for example, recognize military-age males holding weapons? In other words, does the human operator have all the necessary information and the ability to make evidence-based decisions that might prevent unintended victims from being targeted? How good are the systems at distinguishing between combatants and non-combatants? Are they as good as humans?
  • Diverse Behaviors in Non-Uniform Chiral and Non-Chiral Swarmalators
    • We study the emergent behaviors of a population of swarming coupled oscillators, dubbed ‘swarmalators’. Previous work considered the simplest, idealized case: identical swarmalators with global coupling. Here we expand this work by adding more realistic features: local coupling, non-identical natural frequencies, and chirality. This more realistic model generates a variety of new behaviors including lattices of vortices, beating clusters, and interacting phase waves. Similar behaviors are found across natural and artificial micro-scale collective systems, including social slime mold, spermatozoa vortex arrays, and Quincke rollers. Our results indicate a wide range of future use cases, both to aid characterization and understanding of natural swarms, and to design complex interactions in collective systems from soft and active matter to micro-robotics.
