Ask HN: Where do you find weird and wonderful future tech nowadays?
HN has really embraced our current techno-pessimistic culture, so all the things that get on trashed here are definitely worth looking into. And no, I&#x27;m not joking. In the old days, HN had split brain, so things would both get trashed and celebrated - the famous Dropbox thread (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=8863" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=8863</a>)? The top comment is gently dismissive, but overall the thread is also quite encouraging. Twitter is much better, since you can still get the split-brain effect there, rather than isolating yourself in a negative echo chamber.<p>So fining headlines isn&#x27;t hard, I think the real value these days, which didn&#x27;t exist prior to YouTube becoming huge, is that now you can actually really dive into these things in a way that was incredibly inaccessible before.<p>Take self-driving cars: You&#x27;ll see the usual dismissive crap here, but then you can go on YouTube and you can watch Karpathy talk for hours about how they&#x27;re building their system. Then you can go watch someone like Yannic Kilcher talk about Karpathy&#x27;s presentation, explain pappers on which the work is based, etc. Then you can go watch AI DRIVR test the latest iteration in the real world. Because there&#x27;s so much content, you can basically find content at every level, from basic pop-documentary explainers all the way to lectures and paper analysis, allowing you to gradually go deeper and deeper.<p>Rockets and Space? Scott Manley and EverydayAstronaut will explain missions, engines, everything. SmallStars has amazing visuals. EVs? Sandy Munro will tear down an entire car and show you every single little thing in there. Electric Flight? &quot;Electric Aviation&quot; will explain the engineering tradeoffs between Lillium&#x27;s small ducted fans and Joby&#x27;s large propeller design. Biology? iBiology let&#x27;s you dive into any current reserach (Synthic Bio, Connectome scanning, using DNA as structural material). You can just keep going like that for anything, it&#x27;s just plain amazing.
