<p>The problem arises because Trans people in the west (ironically) insist on a binary definition.<p>Here in Pakistan, trans people have fought for (and gained) the right to NOT be part of the binary system; so here we have 'M' for men, 'W' for women and 'X' for trans people. (Homosexuality is still illegal, btw)<p>Or to make it more explicit, the tagline 'trans women are women' would be considered transphobic here, because women is considered to be synonymous with cis women, but they are trans, they earnt the right for that X in their sex column.<p>It's not like we are a bastion of trans rights here, so the issue of bathrooms ( they are required to have their own, iirc, but I doubt compliance is prevalent) and sports (haven't heard anything about trans people in sports) hasn't arisen yet.<p>I feel trans people in the west will have to come to the same realisation that their trans counterparts in the east have; the binary definition is not fit for purpose.</p>

<p>The issue is literally one of segregation.<p>You create, as a form of entertainment for the masses, an event for peak athletes to display their talent...by quirk of biology that means men.<p>You create a women's category to let them have their own entertainment niche.<p>You have in fact segregated sports, by gender, or sex, or whatever you want to call it.<p>Now there exist individuals who challenge the boundaries of this segregation. What do?<p>The realpolitik answer would be to segregate these individuals into yet another niche.<p>Of course the question arises, how many segregation categories to you create before it becomes all meaningless?</p>

<p>Here is Elon Musk's take on this attempt:<p><a href="https://x.com/elonmusk/status/2035743704322023820" rel="nofollow">https://x.com/elonmusk/status/2035743704322023820</a><p><pre><code>    > Given that several companies make advanced chips, but no companies have ever made fully reusable rockets or achieved SpaceX scale, I think Starship is harder, but we shall see.

    > Terafab will technically be two fabs, each making only one chip design. This greatly simplifies process flow and allows more linear, adjacent movement of the FOUP. 

    > A super high production rate allows us to test very quickly what steps can be deleted, simplified or sped up, even after the design is fixed. Current fabs are extremely conservative, operating on rigid historical heuristics, which are mostly, but not all, correct. 
 
    > Anything that is a rate limiter at the machine level means that machine will be redesigned, unless already at limit of physics. 

    > Having new iterations of a chip design be produced every day in the research fab (with <7 day lag) means being able to try out many high risk, high return ideas.

    > Etc

    > In any event, there is no other way to reach extreme scale, so either we make Terafab or we will be stuck at the ~20% chip/memory output growth per year of the current industry.

<p>I want to share this rant by Casey Handmer (Former NASA JPL). I'm sharing the main tweet here, you can read the whole thread in the link:<p><a href="https://x.com/CJHandmer/status/1969634998144888999" rel="nofollow">https://x.com/CJHandmer/status/1969634998144888999</a><p><pre><code>    > It's absolutely insane that this @nytimes article would quote Doug Loverro saying "I was not firm enough in pushing what I should have pushed" when in fact the reason he abruptly left NASA in May 2020 (after just 6 months on the job) was that he was caught providing illicit inside advice to Boeing regarding the Human Landing System contract during the blackout period, despite which Boeing's entry was so poor it was withdrawn. How much harder could he have pushed?

    > It gets even crazier. 

    > The article also quotes Douglas Cooke, who oversaw the Exploration Systems Mission Directorate at NASA from January 2004 until September 2011, and who is thus directly responsible for Constellation's abject failure, cancellation, the debacle of the Ares I-X rocket, and the origins of the SLS program, and who as recently as late 2021 was still advocating for a retvrn to the Constellation architecture (https://x.com/jeff_foust/status/1448008434478108676).

    > Dan Dumbacher rounds out the trio of former NASA executives brave enough to go on the record, as the Deputy Associate Administrator of Exploration Systems Development from October 2010 until July 2014, ensuring this article quotes exclusively from former NASA leaders who have proven beyond doubt they cannot run a rocket development program, and who, having spent 20 years and $100b on their own failed system that somehow forgot to develop the lander, are now throwing stones at SpaceX for spending less than $3b (along with $10b of their own money) and having developed a rocket that's roughly 100x cheaper and 4x more powerful than SLS in less than 1/4 of the time. 

    > I don't want to hear from Loverro, Cooke, or Dumbacher unless it's a detailed explanation of how, exactly, NASA managed to screw up SLS as badly as they did. Perhaps they can ask for an internship at Starbase to get the elite program management exposure and experience they so evidently lacked when the nation entrusted them with the future of the light cone?

    > According to public disclosures, none of these former NASA officials, who now work as independent consultants, receive money from Boeing. And yet whenever their opinion is solicited, they seem to advocate for mission architectures that support Boeing's proposals, Boeing's contracts, and Boeing's interests, despite NASA's own Office of Inspector General finding over and over and over again that Boeing and NASA's program management have collaboratively presided over an extremely expensive comedy of errors. 

    > Not just expensive - as I have now warned for many years - corrosive to US technological dominance and security, as China moves decisively towards the Moon.

looks like there has been infighting among former NASA employees about who is responsible for the decline.</p>

<p><p><pre><code>    > To assemble what would become one of the most important parts of Elon Musk’s Crew Dragon spacecraft, the docking system that would attach it to the International Space Station, a couple of SpaceX engineers in 2013 purchased mountain bike shocks from an online cycling shop. They bought the rest of the parts from McMaster-Carr, a sort of Home Depot for industrial tools and materials and dubbed their creation the “McDocker."


    > NASA’s engineers were perplexed that SpaceX would even go through the trouble of building a docking system on its own. The space agency had been working to design one for more than a decade, in partnership with Boeing, and NASA had offered it to SpaceX for free. Docking with the space station was a perilous task, and NASA was confident its system would work safely. All SpaceX had to do was install it.

    > At other companies, such a thought would likely have been laughed at. A young engineer was going to improve on NASA’s design? Why even bother?

    > When their prototype was finished, Matthews and Western showed it to Mark Juncosa, one of Musk’s most trusted engineers. Unlike some at the company, who shied away from dealing with Musk directly, Juncosa was unafraid of the boss. He told Matthews this was something Musk would want to see and that they should go show him the prototype that instant. Without an appointment, they rolled the McDocker over to Musk’s cubicle and asked him to take a look.

    > Musk studied it intensely, pulling and pushing on the docking ring, while rubbing his chin. After just a few minutes, he said, “Yep, let’s do this.” There were no deliberations. No consultations with other engineers. No memos or meetings. Musk liked what he saw and simply made the decision to go.

    > NASA was incredulous that SpaceX was rejecting its soft capture design and attempting to build something on its own.

    > To be assigned to fly on SpaceX, then, was at best a dead end, many in the astronaut corps believed — because those astronauts would never fly. It might even be a death sentence —because if SpaceX did fly, the thinking was, “If they don’t kill you, you’ll be lucky,” Hurley said. “There were probably five people in the entire agency that thought we’d be successful.” SpaceX would treat you like cargo, Hurley was told. You’d be little more than a “biological payload.”</code></pre></p>
