  • I’m actually not surprised this is possible. The thumbnail might just be a bad raw image of unrelated or unfiltered data. The UWB spectrum can be used for radar purposes to an absurd accuracy. We’re talking sub-mm measurements. Bringing this to the wifi spectrum seems within the realms of possibility as the frequency is pretty similar. The difference is UWB radar is typically used in close quarters with a fixed radar where as the wifi source is probably further away or moving on a mobile phone or wearable.




  • Beyond the obvious CGT and negative gearing loop hole, we really need to look at zoning. Developers continue to buy up land in the furthest suburbs and subdividing it into low density residential (with government approval). Our zoning regulations are completely bizarre and we need to start ending the dichotomy of big land far away vs apartment closer in, so that we can have cheap apartments further out. It’s wild to be that they aren’t massively developing the regions at the end of metro lines to encourage outbound commutes and building high density residential in these areas as well.





  • When an overwhelming proportion of the population is elderly, an overwhelming proportion of the working age populations earnings have to will go to support them. This is measured by an economic ratio known as the dependency ratio which is going to get out of hand for countries like Japan. The strain on public finances paying for pensions and healthcare reduces quality of life for everyone in the country and depresses economic growth as young people working to support the countries elderly population and their own parents have less to invest in the wider economy.


  • Foundation is one of my favourite books, and I hated the TV show for not following the plot of the books more closely. I didn’t mind it if I pretended it was just inspired by foundation but it is so different it almost could have been named something else and had the slight nods to the book cut. The thing that was so fun about the foundation books was the way everything ‘just worked out’ in the end according to the plan, and then seldon pops out and basically says ‘told you so’. That entire concept is missing which basically makes it not foundation. It’s also making every effort to preserve cast through eras with contrived means. I gave up on it part way through S2, though all the seasons are getting pretty decent reviews.


  • We could definitely move into industry in space, but a lot of technology still needs to be developed. I think we now have the capacity to launch factories in pieces into space, but asteroid mining remains a technical challenge due as we now know that many asteroids are not so compacted. Furthermore, refining the raw materials in space can’t really be done right now, we probably could figure it out, but parts of the production chain do depend on gravity so we’d need to figure out artificial gravity on a rotating station or do some more direct kind of centrifugal refining. All hurdles we could probably cross. Then comes the question of what you drop back down from space and how you do it. Current heat shield technologies are generally poorly reusable, and even if we were we’d have to be flying the reentry devices back into space. Unless we create a cheap means to protect something from reentry that can be manufactured in space as a disposable, most goods would never be returned to earth. Unless we just refine giant cubes of rare metals and drop them into the ocean to be collected. I think most things made in space would be limited to serving those in space, or in lower gravity locations such as the moon or other asteroid bases. I would love to work on these challenges but there’s very few companies working on these challenges outside of a couple of asteroid capture startups that seem to have no further vision.
