<p>I watched this last week.<p>The part about veering constantly to navigate the maze of internal politics is fascinating. The compromises he had to make, like not being able to put in on Github initially. The easy victories, like making TypeScript open source.<p>The long road to success. The obligatory advice for people writing new programming languages (Hint: Mostly, don't.). His opinion about creating a new language for AI (I agree with his insight, but still think it is possible).<p>Overall, well worth watching.</p>

<p>I use version managers for Python, Node, Ruby, and others. But for Java, none. I have all the recent versions of Java on my Linux and Windows devices. I download the zip and extract it to a common directory "Java". Setting the path within IDEs is easy, and is mostly unavoidable (regardless of a version manager). Running standalone programs is not that complicated too.</p>

<p>Observations and personal opinions, after glancing through the slides:<p>* The entertainment industry will be transformed drastically. Music and movies will be transformed by AI to such an extent that the next generation will find it hard to believe how the industry operated.<p>* The moonshot will be biological research and research in general. When a breakthrough happens, it will transform our health for the better in astonishing ways.<p>* In terms of direct adoption, the urban-rural divide is vast.<p>* Less democratic countries will have an advantage over the democratic countries in terms of fast execution, unless the latter manage to integrate private-public operations effectively.<p>* I've liked Mary Meeker's reports since the heydays of TechCrunch. This report has a lot of details that I did not know. Nevertheless, I didn't see a single point that stood out.</p>

<p>As far as I understand it, they used 25 human and 12 squirrel samples. Comparison was done among medieval red squirrel strains, medieval human strains, and modern red squirrel strains.<p>Finding: medieval red squirrel strains were  closer to medieval human strains than to modern red squirrel strains.<p>Inference: In medieval England, leprosy spread between red squirrels and people.<p>Problem with the inference: If they used modern human strains too and then compared them all, it would have been a complete study.<p>Are modern red squirrel strains closer to modern human strains than to medieval red squirrel strains? What kind of differences are there? Is it that they evolved independently from medieval times to modern times and thus appear different? Lots of questions are unanswered.</p>

<p>I cannot edit this anymore. Yes, meant that the control Aptiv had over Motional will now be with Hyundai, practically.<p>The point I was trying to make was that this was titled in Aptiv's Q1 presentation [1] as "APTIV EQUITY INTEREST TO BE REDUCED FROM 50% TO 15%". That is, they will offload most of the control to Hyundai. Immediately, Aptiv shares rose. So for some reason, this is seen as a good thing by Aptiv shareholders.<p>My point was and is: Considering the above aspect, it will be interesting to see how Hyundai will make use of it.<p>[1] <a href="https://s22.q4cdn.com/336558720/files/doc_presentations/2024/05/Aptiv-Q1-2024-Earnings-Presentation.pdf" rel="nofollow">https://s22.q4cdn.com/336558720/files/doc_presentations/2024...</a></p>

<p>The story starts with Genghis Khan's plunder of Merv and the mass murder that was ordered by him. It mentions the artisans who were kept alive. Then it swerves to the plunder of Merv by the Oghuz, continues in the next paragraph, and then returns to Genghis Khan by announcing his death.<p>Again, it returns to the artisans,but mid-paragraph (as is typical in that article), switches to battles again, and returns yet again to silk and artisans.
At last, it connects the battles and the silk together.<p>This is probably why it appears very hard to read. Especially, the mid-paragraph context switches continuing to the subsequent paragraph.<p>Nevertheless , a fascinating read.</p>
