- A documentary on the development of the blue LED (https://youtu.be/AF8d72mA41M) was recommended as a case study in how subtle gas-flow and “showerhead” inlet geometry in CVD reactors can dominate process outcomes, illustrating the importance of fluid-dynamics modeling even in apparently simple thin-film growth.

- Figure 01’s new humanoid robot bartender demo (https://youtu.be/Sq1QZB5baNw) sparked a debate on “robo-racism,” the uncanny valley, and whether Asimov’s fictional robots were ever meant to have blank, faceless heads rather than human-like faces.

- Discussion of blockchain-based timestamping compared OpenTimestamps (a merkle-tree scheme anchored in Bitcoin with near-zero marginal cost) with earlier deedbot-style services, highlighting trade-offs between operational expenditure, verification simplicity, and long-term sustainability.

- A link to a recent paper on anomalous isotopic ratios on Mars (https://www.scirp.org/pdf/ijaa_2023062115280080.pdf) was shared, prompting recollections of John Brandenburg’s now-missing Mars Society talk in which he reportedly calculated multi-hundred-kiloton nuclear yield signatures; participants noted the talk’s apparent removal from public archives.

- AnandTech coverage of the first DNA data-storage specification (https://www.anandtech.com/show/21304/first-dna-data-storage-specification-released-first-step-towards-commercialization) was criticized for “very linear thinking” that fails to exploit DNA’s inherently parallel, volumetric storage potential.

- Survey data showing AI researchers’ median estimate for human-level AI shifting from 2059 (2022) to 2040 (2023) prompted sarcastic commentary on the accelerating consensus and the implied crossing point when 100 % of researchers expect arrival “yesterday.”
