Sigh... Look I did not mean to upset anyone. My point was that the Eldar and the Necrons could consistently do more impressive things like craft gods or snuff out stars. This is not me taking the side of the Eldar. I'm just sick and tired of humanity being special snowflakes in sci-fi and so I'm naturally inclined to argue against it in 40K, something for which I think there is a lot of lore backing.
Here's my interpretation of things:
Human in the DAoT just before the MoI Rebellion actually had a chance of eclipsing the Imperial Eldar within a few thousand years. Or at least, have some of their technology eclipse the Eldar. Why aren't there other races that are just as advanced as the Eldar and Necrons in the galaxy given that the Eldar mostly sat around and didn't advance their technology much, if at all, in the 60 million years since the War in Heaven?
With the Eldar, it was because the moment that another race actually got to the point that they could threaten the Eldar, then the Eldar Empire fell on top of them. Sure, the other race may have a hand-gun that can shoot through anything, a fighter jet that can't be seen by anything and a cruiser that can take out dreadnoughts... But the Eldar have all that...
and everything else as well. Which leaves the 'Possible Super Race' either exterminated or smashed down to a much smaller empire size, with the uh... 'understanding' that they advance their technology to
this point, and no further, or "We'll be back to... 're-educate' you lot? Okay"
As for the Necrons and Orks... Yes, they still existed, but this was mostly because the Eldar Empire took a relaxed 'out of sight/foresight, out of mind' stance to them. Or in other words, if a farseer/explorer got curious one day and went looking around the galaxy and found a Necron Tomb World, well, then they went and destroyed it. But they didn't actually dedicate the effort needed on a societal effort to wipe them all out. Especially as the Necrons specifically built their tomb worlds in places to neutralise as many advantages the Eldar had to finding them as possible.
With the Orks, it was more a case of 'small' Ork infestations, whilst still an existential threat to basically everyone else in the galaxy, weren't to the Eldar... So they either wiped out the leaders when the threat grew to the point it might hurt the Eldar Empire, thus causing the Orks to fall into a civil war... Or they directed an Ork Threat that would harm the Eldar to go off in
that direction, bump into that expanding Empire and be mostly shattered themselves. Who cares if it means that race get's exterminated, or almost so, it's not like it harmed any Eldar, now is it?
Humans got lucky. By the time they had started to endanger the Eldar Empire with their technological progress, and size of their civilisation, the Eldar Empire had mostly gotten distracted 'murder-fucking' Slaanesh into existence. That doesn't mean that a tiny fraction of the Eldar living around then didn't mess with the DAoT humans, hell, one of the reasons for the MoI Rebellion could have been something caused by an Eldar not wanting Humanity to endanger the Eldar's supremacy over the galaxy.
To borrow from my favourite explanation for what caused the MoI Rebellions (Non-canon, but it's definitely something I could see being the explanation) "The thing that caused the Rebellion was when a couple of Eldar decided Humanity had to go... Or at least, not threaten the Eldar Empire in the future, what with how they'd soon have access to the Webway and technology that stood a half-decent chance of holding up against that of the Eldar. So they did the
one thing that Human AI designers had never thought possible when developing the Men of Iron, despite having 20 thousand years of fiction about Robot/AI rebellions. They summoned fucking Daemons into the AI cores. Humanity naturally panicked
the fuck out, so when a Martian technology corporation based at the Noctis Labyrinth (you know, near that captive C'Tan) released a patch that disabled the MoI's emotions/emotion emulators, and thus sealed that previously-unknown security flaw, they didn't spend the time to think about what
new problems might occur thanks to that patch.
Unfortunately for humanity and the MoI, it did in fact add a new problem. Because the MoI now knew just what a threat Chaos was. So they investigated and discovered the perfect way to defeat that threat permanently! Even better! They could 'save' the human race along the way! Step One: Exterminate the Human Race, preserving genetic and cultural data so that they could revive the human race after they'd defeated Chaos. Step 2. Commit galactic omnicide. Step 3. Wait for Chaos to disappear and the Warp to return to it's Not-
completely-fucked-up state. Step 4. Revive Humanity and celebrate saving humanity!
Naturally, humanity... disagreed with the MoI's new plan. Rather violently in fact. The MoI knew this would happen, so did a first strike. Hello Men of Iron Rebellion... Unfortunately for the MoI, they lost. Unfortunately for Humanity, this war meant that now they had no chance of defeating the Eldar Empire and thus stopping the birth of Slaanesh, whose creation was now noticeably causing problems in the warp, such as making warp travel near the Eldar Empire.. 'problematic'... 'Warp Storms for Days' problematic.
Unfortunately for the Eldar who started this whole mess, this also meant that the MoI would no longer attack the Eldar Empire and wake them out of their 'let's murder-fuck a Chaos God into existence!' mood, whilst still ultimately being defeatable by the Eldar.
Or simplified: Post-War in Heaven, the Necrons were in a coma, the Orks were having a party but got thrown in jail whenever they made enough of a mess that it disturbed the upper-class residents of the city, and the Eldar were the upper-class of the city, but were all hippies. At least, until they decided to combine Hippy with Goth, and eventually read the wrong page of a tome of eldritch lore, tore a massive hole in reality in their city, consuming the upper-class neighborhoods of the cities and feeding all their souls to the eldritch monster they summoned.
Humanity had the fortune of being a middle-class family trying to break into the upper-class in the city at this time, when all the Eldar were distracted being hippy-goths to each other, and thus didn't notice their efforts and lock them out like they did to all the others before them. Unfortunately, one of the sons in the family went insane about this point and tried to murder the whole family. He was killed in self-defence, but not before murdering most of the family. The remaining members of the family started to think about what to do now, and how to heal, but then the god-damn Eldar tore a fucking huge hole in reality and the entire city went to hell.
You either have an atemporal targeting system, or you don't. And even if it was "cobbled-together", what do you think prototypes are, exactly? You need to make a shit version of something before you can make a good version. The Orks are just unique because they were engineered with an instinctive understanding of tech, so everything they build is prototypes.
