  • I admire your optimism and I hope you’re correct. At least with the little “city commuters” it probably even makes sense. But lithium battery tech also continues to improve – so catching up with 2021 is great, but the goalposts keep moving.

    There will be an absolute limit coming from physics and chemistry, and lithium is a smaller, lighter ion. In the theoretical limits, it will absolutely be the winner.

    But from a practical perspective, if Na-ion becomes light enough and (more importantly) cheap enough, it will probably win the economic game in the longer term.

    Plus we can make Na-ion batteries in-situ elsewhere in the solar system without having to first finding concentrations of lithium – so high tech space industry stuff will likely more towards Na-ion, which will fund some development.




  • I’m actually surprised it has taken this long.

    What surprises me even more is that organized crime hasn’t gotten on board much (yet). Like, screw drive by shootings – drone dropped grenades on rival gangs and such.

    Or that drones haven’t been used for “school shooting” type mass casualty attacks.

    Or that foreign countries haven’t snuck in with a sea can full of drones which fan out and attack infrastructure.

    Imagine a cruise missile as a drone carrier that just scatters anti-personnel drones along a flight path, each just finding a person indiscriminately.

    If there’s anything that Ukraine is teaching us, it’s that we don’t have countermeasures (yet). The autonomous versions are even scarier.











  • Early computer aided art and programs I’ve written, dating back decades.

    In the mid 1990s I used ImpulseTracker to create music. The music sucks. But losing the original source .IT files would be heartbreaking.

    Likewise, my first programs, written as a child in MS DOS batch files circa 1991 – basic menu driven interfaces that facilitated launching my installed sharware… I don’t have the games the program points to anymore, but that isn’t the point ;)
